As you start to build up Bitcoinyou are going to want to think about keeping it secure. There are two basic choices — either let someone else protect it for you, or protect it yourself. As the owner of a Bitcoin mining operation, I earn Bitcoin every day. I buy equipment using Bitcoin.
I have daily experience using it as a currency, and also need to save Bitcoin for the future when the next hardware upgrade cycle comes around.
My advice is based on what I do with my own Bitcoin. There is no actual token or coin that can be placed in a wallet. A Bitcoin wallet refers to a software application that lets you send, store, and receive Bitcoin. The Bitcoin blockchain is a very long and cryptographically secure transaction record, updated every 10 minutes.
In order to participate, your wallet software program generates a private key and a corresponding public key. These keys are used to generate Bitcoin addresses. When someone pays you in Bitcoin, they are using their private key to sign a transaction that sends a certain amount of Bitcoin to an address you control. Your wallet app shows you have a certain amount of Bitcoin that you can spend based on the transaction inputs received by your public address.
The transaction gets included in the next 10 minute blockchain update, and after 5 more updates, or 1 hour, the transaction is fully verified. Bitcoin nodes are computer servers owned by people all over the world, that contain a complete copy of the entire Bitcoin transaction record. There are tens of thousands of these nodes run by many different people and organizations, of all nationalities.
The Bitcoin you control, and can spend, can hack bitcoin wallet 2014 nba 2k17 traced back through the chain of transaction ledger blocks all the way to when it was created. New Bitcoins are created every 10 minutes in the transaction block. Hack bitcoin wallet 2014 nba 2k17 they are created, they are passed around from person to person. Every time they are sent from one person to another, the transaction is recorded in the Bitcoin blockchain ledger. Anyone can view and analyze this transaction record.
Thankfully, your wallet can generate many different public addresses from your one private address. You can use a different one for every transaction, if you like.
Even though it takes an hour to fully verify the transaction, other Bitcoin wallet apps can see the transaction was sent within a few seconds of sending.
Bitcoin wallet sounds friendlier than private key. But the important piece of information as far as Bitcoin goes is the private key. Control the private key, and you can spend all the Bitcoins that private key has control over. They enter the Bitcoin world through an exchange that converts fiat currency, like US Dollars, to Bitcoin. Coinbase and Kraken are good examples of this. Exchanges seem like banks, and people are comfortable with them.
There is a lot of security, including usernames, passwords, two factor authentication 2FAencrypted email, vaults for cold storage, ID requirements, insurance. Unfortunately, sometimes there is too much security. If you start bringing in a lot of Bitcoin, your exchange will even ask for ID, copies of lease documents, pictures of your business, and even your power bill! If you keep your Bitcoin at an exchange, they control the private key. In that way, it really is like a bank.
With an exchange, just like a bank, there is hack bitcoin wallet 2014 nba 2k17 risk. Counterparty risk happens when you have your Bitcoins held by someone else. You have to trust that when you ask for them back, they will give them to you. This usually happens just fine, but might be delayed, or not hack bitcoin wallet 2014 nba 2k17, for any number of reasons.
It is the same counterparty risk you run with a bank. You deposit your dollars in a bank, and trust that when you ask for it back, you can have hack bitcoin wallet 2014 nba 2k17. So far, no one in the USA has had a problem with banks. Well, not much anyway, and those that did, got the taxpayers to pay them back via the FDIC program. Bitcoin exchanges have been hacked, with the private keys hack bitcoin wallet 2014 nba 2k17. Bitfinex was the latest large exchange to get hacked, and it will probably happen again somewhere else.
Gox is probably the most famous exchange that was hacked. When an exchange gets hacked, someone figures out the private keys of the customers, then uses those keys to send themselves the Bitcoin.
And if you do get screwed, try to set things up so you minimize the pain. The first thing to do with any Bitcoin exchange is to set up 2 factor authentication 2FA. This is easy to do with your phone. You can set up basic 2FA by having the exchange text you before allowing a withdrawal to happen. A better way is to use the Google Authenticator app on your phone, which provides a new six digit code every 20 seconds. I use 2FA on every exchange and online wallet account I have.
What you are looking to protect against with 2FA is someone putting a keylogger on your PC, capturing your username and password, then using that information to spend your Bitcoin. When I use exchanges, I am sometimes frustrated by all the actions I have to take to verify my identify. With Coinbase, every week or two I have to accept an email and click a link.
Same thing with Kraken. But taking all these steps only helps make sure my account is not accessed by someone else. It does nothing to protect against counterparty risk. I hedged that risk by using five different exchanges and online wallets. As they say, Hope is not a Strategy. I was still unsatisfied.
I moved away from using exchanges and web wallets altogether for primary Bitcoin storage in hack bitcoin wallet 2014 nba 2k17 of Software Wallets. Electrum let me set up different wallets, and I could send and receive Bitcoin whenever I wanted.
When you create a hack bitcoin wallet 2014 nba 2k17 with Electrum, you encrypt it, and get a 12 word passphrase to recover the wallet encryption. I backed up my wallet to an external drive, and to a USB stick. I figured since I am an IT professional with decades of experience, I would be OK with keeping my Bitcoins secure in a software wallet.
The most common way a computer gets hacked is a trojan dropper downloads a payload application and joins the computer to a botnet. The personal information and keystrokes get uploaded to the control server, hack bitcoin wallet 2014 nba 2k17 it is automatically scanned, and all usernames and hack bitcoin wallet 2014 nba 2k17 recorded. These usernames and passwords are piped to other applications that run them against available internet sites.
Bitcoin software wallets are especially nice finds for the people that run these operations. I got nervous about access to the 12 word passphrase. I printed it out and put it in two different safes. Then I created an encrypted virtual hard drive on my computer with VeraCrypt open source application put the passphrase in a text file in the VeraCrypt file, and made copies of that file. I copied those files to multiple USB keys, and put those in different safes. Then I worried about forgetting the password to the VeraCrypt file!
Finally, I figured I would store the Veracrypt passwords in my online password manager, which is also encrypted. Then I worried about someone getting access to my PC, opening up the Electrum wallet, and sending the Bitcoin to themselves. I also installed the wallets on a dedicated Linux laptop that has an encrypted hard drive, just in case I lost my PC. I also worried that one of my computers might have a virus on it that runs a keylogger and someone could figure out my passwords.
If they were able to copy my Electrum wallet and get my password when I sent Bitcoin, my Bitcoin account could be stolen. Every day I opened my Electrum wallet to make sure my Bitcoin was still there. I was starting to worry about it at night. That was not good. Clearly, standalone software wallets hack bitcoin wallet 2014 nba 2k17 not going to work for me. Finally, I looked into hardware wallets. I had always thought they were silly toys. Boy was I wrong. They are the Holy Grail of Bitcoin storage and use.
There are three main hardware wallets worth looking at: TrezorKeepkeyand Ledger Nano S. They all do the same basic thing, but in different ways. They create the cryptographic private key on the device itself. This takes all the concern about hacking and trojans away. If I want to spend Bitcoin that is secured by a hardware wallet, I open up any wallet app on my PC that can work with a hardware Bitcoin wallet. I type a PIN code directly onto the hardware wallet itself, using buttons on the device.
Then I give permission for the PC wallet app to access the public Bitcoin wallet address on the hardware device. At that point, I can see how much Bitcoin I control, and a transaction history. The hardware wallet also is responsible for signing spending transactions.
