Fire coin is a bitcoin trading platform. As of the end of 2016, the accumulated turnover of fire coin reached 200 billion yuan
bitcoin is a virtual encrypted digital currency in the form of P2P
Bitcoin is different from all currencies. Bitcoin does not rely on a specific currency institution. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction

private keys and assets are transferred to the wallet for centralized management. Users don't need to worry about the loss of the private key of this kind of wallet procts, resulting in the loss of funds; However, the capital risk will be more concentrated in the wallet project side and server side. When the centralized wallet is conquered by hackers, users will suffer unnecessary losses
decentralized wallets, commonly known as onchain wallets, have private keys maintained by users and assets stored in blockchains
decentralized wallets are often referred to as onchain wallets. The private key is handed over to the user. If the private key is lost, the wallet will not be able to help the user recover, and the funds will be lost forever. But the decentralized wallet is difficult to be attacked by hackers, and users don't have to worry about the self stealing of the wallet service provider
centralized wallets are where assets are stored, while decentralized wallets are where private keys are stored
except for the exchange, it is not recommended to use the centralized wallet, although losing the private key may help you find it. But there is always a risk that the company will run
a decentralized wallet is equivalent to a channel, a channel where you can master mnemonics to control your assets on the blockchain. For a decentralized wallet, the most important thing is to protect the security of the [private key]
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

a bitcoin address is a string of 26 to 34 letters and numbers
it looks like a lot of messy code. To put it bluntly, it's like your bank card number
all transfer records of each bitcoin address can be checked through blockchain query, which is open and transparent

1. Delete the wallet by mistake
this is the same operation as I do. What should I do in case of this kind of thing? In fact, as long as you remember the private key, download a wallet again, import the private key and reset the password of the wallet
2. The mobile phone is missing or broken
if your mobile phone is stolen or broken, as long as the private key or mnemonic word is still there, you can download a wallet again, import the private key (or mnemonic word) and recreate the wallet
3. The private key is forgotten, but the mnemonic (or JSON file) is still there
if your private key is lost, but the mnemonic (or JSON file) is still there, don't worry, mnemonic can help you retrieve the private key,
4. The private key is forgotten
the wallet hasn't been deleted. If your private key is forgotten, but the wallet is still on your mobile phone, it's very easy to do, You just log in with your password, enter your wallet, and back up your private key
5. The private key, password and mnemonic words have been lost
sorry, no one can help you
6. Forgotten password or wrong input
this is the same as some other apps that we usually log in. If we forget password or input error several times, click forget password to retrieve it. Back to the decentralized wallet, we need to use the private key or mnemonic words to import the wallet to reset the password
7. Forget the mnemonic words
import the wallet with the private key and back it up again
8. Keystore forgotten
if your wallet is not deleted, this is the same way as if your private key is forgotten but your wallet is not deleted, that is, log in with your wallet password and make a new backup; But if your wallet is deleted, that is, it is unloaded, you need to import the wallet with mnemonic words or private key to backup the keystore again!
First of all, you should imagine a concept of "wallet" in your brain. Your bitcoin is in your wallet. A wallet can contain many... Many addresses. The form of the address is the form
with the bitcoin address generated in the bitcoin wallet, you can receive bitcoin from others, and you can also transfer the bitcoin in your account to the bitcoin address of others. Bitcoin address, like bank card number, has the functions of payment, transfer and withdrawal. However, when transferring money, you can only transfer money by knowing someone else's bitcoin address
if we simply compare a bitcoin wallet to a bank card account, then the address of the bitcoin wallet can be regarded as a bank card account number. The difference is that bitcoin addresses can not be stored on the network, but also exist independently of your wallet
bitcoin address is a string of 26 to 34 letters and numbers. It looks like a lot of messy code. To put it bluntly, it's just like your bank card number. All transfer records of each bitcoin address can be checked through blockchain query, which is open and transparent
address generation of bitcoin Wallet: 256 binary digits are randomly selected to form the private key, and then the address is generated by encryption function. This generation direction is unidirectional. That is, you know that the address cannot be decrypted to calculate the private key. At present, the computing power of human computer can't be cracked, so you can publish the address on the Internet with ease

the value of bitcoin:
1. Avoid war, keep value, etc. If a country is in chaos, bitcoin will become the first choice for many people. Although gold is more stable, it is not convenient to carry. If the country is in chaos, who dares to carry a lot of valuables out? But bitcoin is different, as long as you remember the key of the wallet (many wallets are written with mnemonic words), even if you go empty handed, arrive at a safe place to download a wallet, and enter the correct key to take it out
2. It is used in some gray instries. For example, in the year of 17, the global computer virus blackmail event was bitcoin for blackmail
of course, there are others, mainly these.
If you import mnemonics and find that the generated wallet address is a new one (which is inconsistent with the previously expected one), there may be three cases that need to be investigated one by one
case 1:
first of all, you need to verify whether the mnemonic words backed up before are wrong. Because imtoken can manage multiple wallet addresses, suppose you have two wallet addresses a and B in imtoken, and you want to back up wallet a, but you remember the mnemonic words of wallet B, then you are backing up wrong
Test Method:
myetherwallet can be used for cross validation. Myetherwallet is also a decentralized wallet, which supports the import of mnemonics. However, it should be noted that since myetherwallet is a web wallet, there will be many phishing websites, so users should pay attention to the authenticity of the website when logging in to myetherwallet, so as not to enter the phishing website by mistake and lead to asset theft. Log in to myetherwallet
if the address generated after you input mnemonics into myetherwallet is consistent with the address generated on imtoken, you can be sure that the backup error occurred when you backup mnemonics
case 2:
secondly, you need to make sure if you the mnemonic words incorrectly. If you the mnemonic words incorrectly, it is extremely possible to generate a new wallet address. The verification method is the same as the previous method, which uses myetherwallet to see if the generated wallet address is consistent with the address on imtoken
case 3:
in addition, it is also possible that you have set up a path. For cognitive problems about the path, you can go to the app help center to learn and view it
