$13,000 in Debit Card Fraud

$13,000 in Debit Card Fraud
Okay, I’ll start by telling you never make your phone password 1111, 2222, 3333, Etc. with the amount and type of information we store in our phones these days. I use FaceTime, but it doesn’t always work for multiple reasons, face being covered etc., so for the easiest, quickest password for this rare occasion for me was 33333. Not smart.
(First 3 paragraphs are the backstory, skip to the 4th to get to the nitty and gritty. Backstory TL;DR I lost one of my phones, thinking It was somewhere at home or accidentally thrown away, wasn’t too worried about it.)
Okay, I am at the end of my wits and starting to get extremely frustrated at the run around I’m receiving. I have 2 phones and i hate it and have been thinking about getting rid of one of them. The day after Christmas after after multiple family stops the day before and really, what I call, chaos, I realize I can’t find one of my phones. I check find my IPhone and it is offline. Not stressed at the moment, just figured it’s around the house somewhere buried under some wrapping paper somewhere who knows, It’ll show up eventually, plus I finally only have one phone and I kind of enjoy it.
So I leave the next day for our yearly trip to Florida. Still couldn’t find my phone, but didn’t search to hard to be honest. Gone till the 6th. Only find out one problem. My bank account is under the number that I lost, so with 2FA, I can’t access my bank account without that number, still not a big deal, not freaking out. Now I have a few days to find this phone when I get home before I leave on the 9th for another week long trip, but I’m thinking it’s gonna take me 5 min. Get home catch up up some sleep. Tear the house apart, not there. I mean I looked everywhere. Well, Time to leave again. Confused as all hell, but still not that worried. I made plenty of deposits in my bank account and have another at another bank so I’m not needing to check my bank account at all as I know I’m good. Still not stressing it I leave and will finally get it all sorted out when I get home. Not knowing what cluster fuck I had in store for me I had planned on leaving again on the 18th for 4 days and the 24th till the end of January.
Get home. Go to every place I had went on Christmas, even after having them all look, figured I’d look again. Now I’m leaving thinking it must just have been thrown away with all the trash from Christmas and when I get back I’ll just cancel that number, call the bank to switch numbers, and call and switch over all the other accounts I have tied to that number and change them to the new number. Which is quite a few. Probably why I have been putting it off for so long. Finally decide I’m gonna stick with 2 numbers. Just going to get me a new phone with the same number when I get home and we’re all good.
Okay that’s the backstory of how it took me so long to notice what had been happening to me the whole time. Now to the good stuff. Get my number back. Everything’s good right? Wrong. I go to log into my bank account and the number and email address are changed. I immediately contact the bank to let them know and cancel my debit card and credit cards and tell them everything that has happened, also find out there had been $13,368 in fraudulent charges on my debit card, which I had in my possession the entire time. After reporting the fraudulent charges to capital one, they said they would investigate, I had also emailed the company to let them know of the charges and requested documents on all of the charges and told them I would be more than willing to help in anyway I can or give them any documents they would need to help with the investigations. I told Capital One the same thing. As I wait on a reply through my own investigation.
I had recognized the company that my card was charged to as one that I used to buy cryptocurrency through an exchange that I had previously used called KuCoin. So I did my own research turns out my phone didn’t get thrown away because the only way this could have happened is if someone had found my phone. I have all my account info for everything along with my debit card and credit card numbers, CVC, I mean everything, stored on my phone in documents in the cloud. So they got on the crypto exchange, the only one, that doesn’t have a delayed withdrawal time, or a KYC and 2FA set up (I set it up just to try it out, didn’t do much with it, and went back to Coinbase and Binance) and used my card info to send bitcoin to my account on KuCoin after changing the email and number, and immediately withdrew every deposit as soon as they got it. On Blockchain.com, you can see they were all sent to the same exact wallet, and from that wallet to a few others. They also put money on someone’s account through inmatesales.com with my debit card, so I’m assuming one of their buddies could get some nutty bars, fresh undies, and a phone call or something. I have never previously used this website.
4 Days later I recieved an email from Capital one saying they have concluded their investigation and denied my claim. 4 Days is pretty quick, at least I think as I have never had a fraudulent charge or disputed any charge on any of my accounts, ever, in my life so I don’t know the process. They never asked for any documentation to support my claim, when I started to ask questions and seek information into their investigation they told me I could request a document on how they reached their decision and would not discuss the matter any further. Any question I asked regrading the dispute was answered with “we will not discuss this matter any further”. Literally any question I had was answered with that line. What pisses me off the most was after I told them that all my information was at risk that along with new card number, I would also like to change my account numbers; which were obviously compromised as well. They told me they wouldn’t do that. Wtf. Guess I’ll just close my account then.
Basically what I’m asking is what is the process to getting my money back? Their reasons for denying my claim is that the CVC number was used, I’ve had previous business with the company, SMS confirmation (don’t know what number they are talking about, but either way, I wasn’t in possession of my number, and they changed the number on my account, and the last reason was that my story doesn’t match account or login records (I was never able to log into my account through the entire month due to 2FA security). There’s no way that my story doesn’t match the records because it is what happened and the truth is the truth and facts are facts.
Am I going to have to hire a lawyer and take them to court? If it wasn’t this much money I’d just say screw it and eat my losses and move on but now I’m pissed and it’s about principle now. Am I pretty much screwed at this point?? Let it be known this is only with my capital one account. Which isn’t the only account they were able to get into. They got into my TD Ameritrade account and my fifth third account, both with debit cards. Help me please. I know it might seem like I have enough money to be able to make it through this, but I don’t. I’m actually broke and just barely making it by, and that $13,000 was the most money I’ve ever had in my bank account. :( I’m scared. Please help.
TL:DR. I Lost my phone and the person who found my phone got into all my accounts and swindled me out of $20k.

Money Loves Security And So Do Cryptos: A Brief Guide Down Crypto Wallet Lane

Since time immemorial people have been keeping their money and valuables in safe places. Be they purses, clay pots full of coins buried in their backyards or treasure chests hidden in caves with piles of bones strewn around to keep unwanted visitors at bay, they means conceived for safekeeping hoarded valuables are just as creative as they are limitless.
The advent of cryptocurrencies as a new class of valuables and assets instantly spawned the need to keep them safe from the clammy hands of criminals. The logical solution was to develop wallets that would be used to keep cryptos safe. As a result, a multitude of wallets have emerged offering all kinds of added services to their users while remaining means of storage at heart.
There is a huge variety of wallets available: Coinomi, GreenAddress, Blockchain.info, Atomic, Exodus, Jaxx, Electrum, Copay, Bread, Airbitz, Armory, Mycelium, Blockchain Wallet and dozens of others, each offering their services to suit any taste.
https://preview.redd.it/tai1ax5q3u341.jpg?width=1200&format=pjpg&auto=webp&s=0a33622327c7e52eea02e77f7c843423e6aeba12

Types Of Wallets

There are several types of wallets available to users and everyone must decide for themselves which one suits their needs best.
Hardware wallets: These are the most secure and reliable wallets available, since they are not connected to the internet at all. Hardware wallets are like flash memory cards that store the user’s cryptocurrencies and access offline. A bright example is the Trezor wallet, which is deemed to be impermeable to hackers. Unless the user loses the device itself, it is safe to assume that the cryptos will stay on it indefinitely and no one will ever gain access to them.
Online, Web or Hot wallets: These are online services, or online wallets that offer to store the user’s cryptos online with direct access to the internet at any time. In essence, online wallets are online accounts in which users store their funds. The risks are very high, since exchange wallets are routinely being hacked and the cryptos stored therein stolen.
Desktop wallets: Desktop wallets are software programs that can be downloaded and installed on a PC and will only be accessible from the device they were downloaded onto. The risks are the same as with hot wallets and another added inconvenience is that loss of the device or loss of access to it means loss of all cryptos stored on it.
Mobile wallets: Mobile wallets are software programs that can be downloaded onto a mobile device, such as a phone or a tablet. There are wallets for Android and iPhones and all of them bear even greater risks than hot wallets. Since mobile devices are susceptible to theft and a variety of viruses, it is extremely risky to store cryptos on them. Though access to the cryptos without private keys is impossible, unless the user stores them on the device, loss of all cryptos with the mobile device is guaranteed.
Paper wallets: Paper wallets are offline cold storage for cryptocurrencies. This is by far the safest means of storing cryptos, which includes printing the public and private keys on a piece of paper and storing it in a safe place. The keys are printed in the form of QR codes for convenience. With paper wallets, the user has complete control over their funds and the only risk lies in losing the piece of paper with the keys.
Other types of wallets: Apart from the five main types of wallets, there were attempts at creating other types of services, such as atomic wallets using atomic swap technology and even combinations of mobile/hot/cold wallets. Despite limited success, hybrids models of wallets did not become popular.

Main Pros And Cons

When looking at wallets and their main advantages and disadvantages, it is easiest to speak of the division between cold and hot wallets.
When speaking of cold wallets, such as the Trezor Bitcoin wallet and Ledger Nano S or X, the same issue will be observed, and that is the fact that such wallets can be physically lost. Though anyone who ever finds them will never be able to gain access to the stored cryptos without the private keys (unless they are pasted on the device), loss of all cryptos on the device is guaranteed. In addition, cold wallets can be difficult to install and are inconvenient for frequent use.
https://preview.redd.it/ff2dukdx3u341.png?width=1021&format=png&auto=webp&s=f36cdc26b13f33433c5124f5e5a67c0e40f9dbf4
Hot wallets are far more susceptible to risk than their cold counterparts. Though hot storage is much faster and convenient with a wide variety of options from Coinbase to Blockchain.info, the risk of cybercrime runs high. Mobile or desktop storage is also considered to be hot storage and is also risky, if the device is damaged or destroyed.

Bitcoin Problems

Bitcoin, as the firstborn cryptocurrency, was born with a number of defects. One of the main problems of the king of cryptos is the yet unsolved scalability problem. This refers to the limit on the amount of transactions the Bitcoin network can process due to the limited size of and frequency of blocks in the Bitcoin blockchain.
Said problem poses some difficulties to all Bitcoin users and leads to what is known as backlog in the blockchain. The backlog leads to long queues of transactions in the system. With the average transaction time in the Bitcoin blockchain being around 7 transactions per second and the theoretical maximum standing at 27, it is not difficult to understand how long users of the blockchain have to wait for their transactions to pass in times of heightened demand – the time is in the hours and sometimes even days.

Bitcoin Wallets Review

Since Bitcoin is the most popular cryptocurrency on the market, it is logical to judge wallets by their support of the first cryptocurrency. As such, the following will be a brief review of some of the best and most popular Bitcoin wallets on the market.
Online Bitcoin Wallets
Online or web wallets are the most popular ones out there and the best Bitcoin wallet overall is widely considered to be Blockchain.info, which is easily accessible and convenient for everyday use with good security. As an anonymous Bitcoin wallet, Coinbase follows in the lead with its ability to store a multitude of various coins, but with the same security risks that are inherent to all hot wallets.
Android Bitcoin Wallets
Android is the most popular mobile system in the world and plays host to a number of good mobile wallets. The best Android Bitcoin wallet is widely considered to be the Electrum Bitcoin wallet with its excellent reputation, good security and convenience. Though Electrum has some occasional glitches, they are never critical. Another excellent wallet for Android is the Coinomi wallet with its support for a wide variety of cryptos and excellent user support, which even allows for restore options using special phrases. Coinomi has its issues as well, such as occasional exchange glitches, but the many pros outweigh the cons.
Bitcoin Hardware Wallets
The undisputed leaders as the best hardware wallets for Bitcoin are Ledger Nano X and S, Trezor T and Trezor One, and Keepkey. Bitcoin hardware wallets are comparable in their security, accessibility and usability. The difference is mainly in the price, which ranges from $165 for Trzeor T to $59 for the Ledger Nano S model. In fact, the Ledger Bitcoin wallet is often called the king of hardware wallets. The KeepKey Bitcoin wallet is the in the top three hardware wallets as a convenient and stylish device. Though KeepKey supports over 40 assets, it still lacks coin support.
Bitcoin Wallets For iPhone
iPhone’s iOS system is the second most popular for mobile devices in the world and has support for some good wallets as well. The best iOS Bitcoin wallet for iPhone is considered to be the Abra software, which offers credit card support for topping up crypto balances and a good user interface, which is even more oriented at exchanges. The next software is Edge, formerly known as Airbitz. The Edge wallet is best known for high security and good user-friendliness along with multi-currency support.
Bitcoin Wallets For Windows
Bitcoin wallets for PC are very popular and Windows is leading the way with some excellent offers for wallets. Atomic is by far the most advanced and the best option for Windows users as it offers Atomic swaps technology as its basis. The application offers a wide variety of operations and supports over 300 cryptocurrencies. Exodus is the second most popular choice as a desktop only wallet with support for Bitcoin and many other altcoins. Exodus offers its users a good interface and it is free for use.
Bitcoin Wallets For Mac
Since Atomic and Exodus are cross-platform wallets, they can be used on Windows and Mac. Apart from them, there are also Jaxx and Electrum, which can be used on Mac. Jaxx is a multi-currency wallet with support for around 40 cryptos and has a PIN feature. In addition, Jaxx is free for use. Electrum is one of the oldest desktop wallets and is a lightweight wallet that does not require the full blockchain to operate, meaning less storage needed for its operation. The wallet requires a PIN and is essentially a desktop bank with good security and usability. Electrum is also a Bitcoin wallet for iPad, since it can be used on mobile platforms.
Bitcoin Paper Wallet
Since storing cryptos online on exchange or hot wallets or even on devices is risky, it is oftentimes more convenient to use a simple printer to print out the keys and store them. BitAddress offers a convenient and easy to use, step by step guide to creating a paper wallet with the added benefit of sleeping in peace, known that nothing and no one will ever threaten your Bitcoins.
https://preview.redd.it/bh7wi0d64u341.png?width=600&format=png&auto=webp&s=9f7fbd269eea43ac3b8897ad470553ba8b3c730d

Checklist

When embarking on the journey of creating your first wallet, think well of which type to use. The type will depend on the priorities that stand before the user. If security is paramount, then paper or cold storage wallets are the go-to solution. If frequency of use is the name of the day, then hot wallets and their inherent risks are the best way to go.
The most frequent questions related to wallets are how to add money to a Bitcoin wallet and how to set up a Bitcoin wallet. Both questions have no single answer, as each wallet offers its own instructions on how to top up balances and how to set them up. Therefore it is recommended to study all instructions carefully prior to operation.
Either way, there is no silver bullet and some features will have to be sacrificed in deciding how to store cryptocurrencies. The one thing that is constant is the need to store Bitcoins and cryptos and make use of them.

What is a Cryptocurrency Wallet?

What is a Cryptocurrency Wallet?
Use this straightforward guide to learn what a cryptocurrency wallet is, how they work and discover which ones are the best on the market.
A cryptocurrency wallet is a software program that stores private and public keys and interacts with various blockchain to enable users to send and receive digital currency and monitor their balance. If you want to use Bitcoin or any other cryptocurrency, you will need to have a digital wallet.
How do they work?
Millions of people use cryptocurrency wallets, but there is considerable misunderstanding about how they work. Unlike traditional ‘pocket’ wallets, digital wallets don’t store currency. In fact, currencies don’t get stored in any single location or exist anywhere in any physical form. All that exists are records of transactions stored on the blockchain.
Cryptocurrency wallets are software programs that store your public and private keys and interface with various blockchain so users can monitor their balance, send money and conduct other operations. When a person sends you bitcoins or any other type of digital currency, they are essentially signing off ownership of the coins to your wallet’s address. To be able to spend those coins and unlock the funds, the private key stored in your wallet must match the public address the currency is assigned to. If public and private keys match, the balance in your digital wallet will increase, and the senders will decrease accordingly. There is no actual exchange of real coins. The transaction is signified merely by a transaction record on the blockchain and a change in balance in your cryptocurrency wallet.
What are the different types of Cryptocurrencywallets?
There are several types of wallets that provide different ways to store and access your digital currency. Wallets can be broken down into three distinct categories – software, hardware, and paper. Software wallets can be a desktop, mobile or online.
Are Cryptocurrency wallets secure?
Wallets are secure to varying degrees. The level of security depends on the type of wallet you use (desktop, mobile, online, paper, hardware) and the service provider. A web server is an intrinsically riskier environment to keep your currency compared to offline. Online wallets can expose users to possible vulnerabilities in the wallet platform which can be exploited by hackers to steal your funds. Offline wallets, on the other hand, cannot be hacked because they simply aren’t connected to an online network and don’t rely on a third party for security.
Although online wallets have proven the most vulnerable and prone to hacking attacks, diligent security precautions need to be implemented and followed when using any wallet. Remember that no matter which wallet you use, losing your private keys will lead you to lose your money. Similarly, if your wallet gets hacked, or you send money to a scammer, there is no way to reclaim lost currency or reverse the transaction. You must take precautions and be very careful!
Although Bitcoin is by far the most well-known and popular digital currency, hundreds of newcryptocurrencies (referred to as altcoins) have emerged, each with distinctive ecosystems and infrastructure. If you’re interested in using a variety of cryptocurrencies, the good news is, you don’t need set up a separate wallet for each currency. Instead of using a cryptocurrency wallet that supports a single currency, it may be more convenient to set up a multi-currency wallet which enables you to use several currencies from the same wallet.
Are there any transaction fees?
There is no straightforward answer here.
In general, transaction fees are a tiny fraction of traditional bank fees. Sometimes fees need to be paid for certain types of transactions to network miners as a processing fee, while some transactions don’t have any fee at all. It’s also possible to set your own fee. As a guide, the median transaction size of 226 bytes would result in a fee of 18,080 satoshis or $0.12. In some cases, if you choose to set a low fee, your transaction may get low priority, and you might have to wait hours or even days for the transaction to get confirmed. If you need your transaction completed and confirmed promptly, then you might need to increase the amount you’re willing to pay. Whatever wallet you end up using, transaction fees are not something you should worry about. You will either pay minuscule transaction fees, choose your own fees or pay no fees at all. A definite improvement from the past!
Are cryptocurrency wallets anonymous?
Kind of, but not really. Wallets are pseudonymous. While wallets aren’t tied to the actual identity of a user, all transactions are stored publicly and permanently on the blockchain. Your name or personal street address won’t be there, but data like your wallet address could be traced to your identity in a number of ways. While there are efforts underway to make anonymity and privacy easier to achieve, there are obvious downsides to full anonymity. Check out the DarkWallet project that is looking to beef up privacy and anonymity through stealth addresses and coin mixing.
Which Cryptocurrency wallet is the best?
There is an ever-growing list of options. Before picking a wallet, you should, however, consider how you intend to use it.
Bread Wallet
Bread Wallet is a simple mobile Bitcoin digital wallet that makes sending bitcoins as easy as sending an email. The wallet can be downloaded from the App Store or Google Play. Bread Wallet offers a standalone client, so there is no server to use when sending or receiving bitcoins. That means users can access their money and are in full control of their funds at all times. Overall, Bread Wallet’s clean interface, lightweight design and commitment to continually improve security, make the application safe, fast and a pleasure to use for both beginners and experienced users alike.
Mycelium
Advanced users searching for a Bitcoin mobile digital wallet, should look no further than mycelium. The Mycelium mobile wallet allows iPhone and Android users to send and receive bitcoins and keep complete control over bitcoins. No third party can freeze or lose your funds! With enterprise-level security superior to most other apps and features like cold storage and encrypted PDF backups, an integrated QR-code scanner, a local trading marketplace and secure chat amongst others, you can understand why Mycelium has long been regarded as one of the best wallets on the market.
Exodus
Exodus is a relatively new and unknown digital wallet that is currently only available on the desktop. It enables the storage and trading of Bitcoin, Ether, Litecoins, Dogecoins and Dash through an incredibly easy to use, intuitive and beautiful interface. Exodus also offers a very simple guide to backup your wallet. One of the great things about Exodus is that it has a built-in shapeshift exchange that allows users to trade altcoins for bitcoins and vice versa without leaving the wallet.
Copay
Created by Bitpay, Copay is one of the best digital wallets on the market. If you’re looking for convenience, Copay is easily accessed through a user-friendly interface on desktop, mobile or online. One of the best things about Copay is that it’s a multi-signature wallet so friends or business partners can share funds. Overall, Copay has something for everyone. It’s simple enough for entry-level users but has plenty of additional geeky features that will impress more experienced players as well.
Jaxx
Jaxx is a multi-currency Ether, Ether Classic, Dash, DAO, Litecoin, REP, Zcash, Rootstock, Bitcoin wallet and user interface. Jaxx has been designed to deliver a smooth Bitcoin and Ethereum experience. It is available on a variety of platforms and devices (Windows, Linux, Chrome, Firefox, OSX, Android mobile & tablet, iOS mobile & tablet) and connects with websites through Firefox and Chrome extensions. Jaxx allows in wallet conversion between Bitcoin, Ether and DAO tokens via Shapeshift and the import of Ethereum paper wallets. With an array of features and the continual integration of new currencies, Jaxx is an excellent choice for those who require a multi-currency wallet.
Armory
Armory is an open source Bitcoin desktop wallet perfect for experienced users that place emphasis on security. Some of Armory’s features include cold storage, multi-signature transactions, one-time printable backups, multiple wallets interface, GPU-resistant wallet encryption, key importing, key sweeping and more. Although Armory takes a little while to understand and use to it’s full potential, it’s a great option for more tech-savvy bitcoiners looking to keep their funds safe and secure.
Trezor is a hardware Bitcoin wallet that is ideal for storing large amounts of bitcoins. Trezor cannot be infected by malware and never exposes your private keys which make it as safe as holding traditional paper money. Trezor is open source and transparent, with all technical decisions benefiting from wider community consultation. It’s easy to use, has an intuitive interface and is Windows, OS X and Linux friendly. One of the few downsides of the Trezor wallet is that it must be with you to send bitcoins. This, therefore, makes Trezor best for inactive savers, investors or people who want to keep large amounts of Bitcoin highly secure.
Ledger Nano
The Ledger Wallet Nano is a new hierarchical deterministic multisig hardware wallet for bitcoin users that aims to eliminate a number of attack vectors through the use of a second security layer. This tech-heavy description does not mean much to the average consumer, though, which is why I am going to explain it in plain language, describing what makes the Ledger Wallet Nano tick. In terms of hardware, the Ledger Wallet Nano is a compact USB device based on a smart card. It is roughly the size of a small flash drive, measuring 39 x 13 x 4mm (1.53 x 0.51 x 0.16in) and weighing in at just 5.9g.
Pros:
Cons:
Green Address
Green Address is a user-friendly Bitcoin wallet that’s an excellent choice for beginners. Green Address is accessible via desktop, online or mobile with apps available for Chrome, iOS, and Android. Features include multi-signature addresses & two-factor authentications for enhanced security, paper wallet backup, and instant transaction confirmation. A downside is that Green Address is required to approve all payments, so you do not have full control over your spending
Blockchain (dot) info
Blockchain is one of the most popular Bitcoin wallets. Accessing this wallet can be done from any browser or smartphone. Blockchain.info provides two different additional layers. For the browser version, users can enable two-factor authentication, while mobile users can activate a pin code requirement every time the wallet application is opened. Although your wallet will be stored online and all transactions will need to go through the company’s servers, Blockchain.info does not have access to your private keys. Overall, this is a well-established company that is trusted throughout the Bitcoin community and makes for a solid wallet to keep your currency.

Safest way storing bicoins ?

Is there a 100% safe way storing my bitcoins ?
The recommendation I read most often, in regards to safely storing any cryptocurrencies, is to never store them on an online exchange.
So I have been looking into the alternatives:
  1. Online wallets: I am currently using an iOS app called Breadwallet, which is very easy to use. It is a well recognised application, so you should think it would be ok, in terms of safely storing bitcoins. But I am really searching for the safest way on earth to store these bitcoins. So when I am trusting in Breadwallet storing my private keys, what would happen if Breadwallet got attacked by hackers ? Or if they made a operational faulth. I could potentially loose my asset, right ? And also, if I should have some kind of Malware already installed on my iPhone, the malware could make printscreens of my iPhone screen and therefore they could see my Private Keys, right ? Please correct me if I am wrong.
  2. Hardware wallets: So I see alot of posts of people recommending the Trezor or Ledger Nano S physical hardware wallets. These should according to them, be very safe and there should be nothing in those devices, that could ever be hacked. But what happens, if these devices have hardware failure ? Could I then risk losing access to my private keys ? And also (please bear with me, I am new in the cryptocurrnecy world) when using for example Trezor, am I then relying on a third party (Trezor) to store my private keys and therefor my bitcoins ? So what could potentially happen, if this company got attacked or went bankruptcy or something like that ? Meaning could this be of any threat to the stored private keys and therefore the bitcoins ? Again please correct me if I am wrong.
3: Paper wallets: Also there are a lot of posts recommending going for the Paper wallet solution. And to do it the safest way (as I have understood), would be to go purchase a brand new pc, that has never been exposed to the internet. Then on another pc, to go to bitaddress.org and download that program and put it on an empty usb-stick. Then take this usb-stick and put it into the brand new pc, which is NOT connected to the internet and run this bitaddress program. Meaning offline. Here I would get a public adress and the associated private key. I would then buy a cheap brand new printer, that also has never been exposed to the internet. I would connect this printer, by cable, to the new pc. I can now print out the paperwallet. Now I can start transferring any amount to this public address and MAKE SURE to hide the printed paper wallet, in a very secure place. Or even print out several copies and hide them in different places. Would be a good idea to put it in a plastic bag first, to prevent water from damaging it. Of course I could make several of these paper wallets and spread my amount evenly, if I felt more secure about that.
And now I would make sure, to NEVER connect this pc and this printer to the internet, to prevent any malware to go back in time and see what I have been doing with it.
So now I should feel safe about my bitcoins, right ?
BUT WHAT IF this bitaddress.org, is just a list of private keys, that they already have stored in the program and me believing that they key that I have generated offline, is only known by me. Meaning, that they know have me putting bitcoins in their already predefined accounts ?
Again I could be totally wrong.
I would really much appreciate any advice :)

How to extract the private keys from the Bitcoin.com wallet's recovery phrase?

Hey guys,
I've just explained the basics of Cryptos to someone over the weekend and we used the Bitcoin.com wallet to make some transactions, because it's available on android and iphone and pretty simple to use.
I explained her how important it is to save your private keys. Turns out I couldn't figure out how to extract them from the wallet. It gives me the 12 word phrase.
Can someone post me instructions on how to extract the private key from the 12 word seed please?
The coinomi wallet for android has this offline browser tool that allowed me to extract all private keys from the recovery phrase. But that wallet is not available for the iphone, and I'm sure there must be a way to extract the private keys from the Bitcoin.com wallet.
thanks for the help!
edit:
Thanks for all your answers. I understand now that the recovery phrase is all I need, and a BIP39 recovery phrase can be imported to other compatible wallets to restore my funds there.

Samsung Galaxy S10 – Crypto Wallet Smartphone

Samsung Galaxy S10 Crypto Wallet Smartphone – The mobile from Samsung – the world’s most popular smartphone manufacturer mobile family has been in the news for their new upcoming model, especially with the crypto enthusiasts.
The all new Samsung Galaxy S10 has an inbuilt hardware crypto wallet in the smartphone.
Samsung, South Korea’s biggest and largest business conglomerate has announced on 20th February about its new premier smartphone and that it would have in-built cryptocurrency wallet functionality.
There had been rumours going on for the hardware crypto wallet functionality since others like HTC and Huawei has also done it. Crypto lovers have been waiting to know what will be the good news from Samsung.
Samsung has been in the mobile market forefront for last 10 years with their Galaxy range of smartphones. The Samsung Galaxy S10 is a de facto answer to Apple’s iPhone X models and HTC Exodus with the crypto wallet feature, it seems.
Samsung shipped more than 70 million smartphones around the globe.
With this new feature and the evident Samsung popularity, millions of new users all over the world will get the ability to securely store their crypto wealth in their mobiles.
The new feature should also help once again in the mass adoption of digital assets.
According to the Samsung notification on their marketing website, “Samsung Galaxy S10 is built with defence grade Samsung Knox, as well as secure storage backed by hardware, which houses your private keys for blockchain-enabled mobile services”.

Samsung Galaxy S10 Price and Features

Again, going by their marketing website, Samsung Galaxy S10 models will range from $749.99 USD (Galaxy S10e) to $999.99 USD (Galaxy S10+).
According to Samsung, Knox is their “secure environment” mobile security solution.
Presumably, the Blockchain KeyStore app will support bitcoin and a host of top cryptocurrencies.

Samsung Crypto Patents

Earlier, Samsung has filed three crypto-centric patents with the European Union Intellectual Property Office in Dec. 2018. Those three patents were related to proprietary offerings in the “Blockchain KeyStore”, “Blockchain key box” and “Blockchain Core”. The Samsung Galaxy S10 cryptocurrency wallet capabilities come from these patents.
Samsung has also published an article entitles, “Why Smartphones Have The Best Security For Blockchain And Cryptocurrency” last year. The article said that smartphones were ideal devices to store spendable cryptocurrency.
Smartphone-based cryptocurrency wallets are of good use if we wish to keep the crypto for spending and transaction them. This means using the smartphone crypto wallet for short term holdings and for transactions.
Going by the advice of crypto specialists, it is always good to keep your long term storage of cryptocurrency in a backup and offline mode. This will definitely be safer and securing instead of carrying all your crypto in your mobile.
Let’s go a step further and try to compare the hardware wallets like Ledger NanoS and Trezor with the smartphone wallets.
Personally, I don’t feel the smartphone wallets can replace the hardware wallets. I feel the hardware wallets will be more secure.
Though Samsung Galaxy S10 crypto wallet has come to bang the market, there have been mobile wallets already available from Taiwan based HTC in their Exodus model and Huawei’s pre-installed BTC.com bitcoin wallet in Honor phone series.
Another lesser known, Sirin Labs has also launched its Finney smartphone, offering native crypto storage.
Whatever the future of mobile crypto wallets maybe, but definitely, Samsung Galaxy S10 with its in-built crypto hardware wallet will give a fillip to the market in two ways. 1. Higher adoption of the crypto especially with the upcoming bitcoin lightning network; and 2. Higher acceptability and transaction power to the crypto users.
Let’s hope for the best and all our best wishes to the Samsung Galaxy S10 with their crypto hardware wallet.

Please help! I know the punks who stole my bitcoin!!

I am new and learning but am certain bitcoin is the future. I took my life savings and bought 10btc. I had my wallet on my main android phone and backup copy of my wallet on an old iphone. These 2 new 'friends' i was helping move to Los Angeles, must have seen me use my cellphone password. They stole my old iphone and then used my password to transfer all my 10btc to a different wallet. I tracked that wallet to an ATM in Las Vegas, where they used their own cell phone number to confirm the cash withdraw.
I gave the local cops all the info they need to prove they stole my bitcoin, even the ATM has the footage of them on video. My icloud is offline and cleared out. They are on the run and can be in any state. Their families are in TN and MI. They are 21 & 22. They probably gambled and drank it all away already. I found their facebook and saw they had many arrests for theft & drugs & firearms, but only one conviction ever. Their parents must keep paying lawyers to get them off. I need help to stop them, before the steal more or get people hurt.
The cops are not doing every much. They are calling them daily, no answer, to hear their side of the 'story'. How do i get someone to help stop them?? Ideas?? Please help!! Its all the money i ever had. I realize i made bad mistakes, but what these guys do to others is evil. What do i do now? Any help?
