first enter your email address, and then enter your password twice. After that, enter the verification code
here we should pay attention to: the password should be more than 10 digits, and we must remember that if you lose it or forget it, you can't recover it. It's equivalent to losing your money and you can't get it back

OK, the wallet is created successfully. Print out the following tips or them to another safe place to save them. Maybe you will lose your password one day, which will be of great use.

2. Hello, miner
3. There is no backup private key or mnemonic word. If not, it will be troublesome. Basically, it is impossible to find it.
4. It's basically the same,
bitcoin
trades directly through the wallet. Detailed can go to cnfol bitcoin network to learn how to trade, I don't know.

5. The process of BTC address generation is as follows. You can check bitcoin Chinese wiki completely:
bitcoin address generation process
(Note: some numbers are marked with & quot; 0x" Begin with, meaning that the number is in hexadecimal notation& quot; 0x" It doesn't have any meaning in itself. It's a conventional writing method handed down from C language. For example, 0xa is 10 in decimal system. In addition, 1 byte = 8-bit binary = 2-bit hexadecimal)
in the first step, randomly select a 32 byte number and size from 1 to 0xFFFF ffff ffff ffff ffff ffff ffff fffe baae dce6 af48 a03b BFD2 5e8c d036 4141 as the private key
in the second step, the elliptic curve encryption algorithm (ecdsa-secp256k1) is used to calculate the uncompressed public key corresponding to the private key A total of 65 bytes, 1 byte is 0x04, 32 bytes are x coordinates, and 32 bytes are y coordinates
the third step is to calculate the SHA-256 hash value of the public key
the fourth step is to take the previous step result and calculate the ripemd-160 hash value
the fifth step is to take the previous step result and add the address version number (bitcoin main network version number "0x00")
00
the sixth step is to take the previous step result, Calculate the SHA-256 hash value
Step 7, take the result of the previous step, and then calculate the SHA-256 hash value (HA HA)
Step 8, take the first four bytes (8-bit hexadecimal)
d61967f6
Step 9 of the result of the previous step, and add these four bytes after the result of step 5, As a check (this is the hexadecimal form of the bitcoin address)
00d61967f6
Step 10: change the address with base58 notation (this is the most common form of bitcoin address)< br />

6. If you want to mine, you need to join the mine pool. You can't find bitcoin without adding the mine pool. Jersey mining has mining areas all over the world.
7. First, confirm whether the recharge address of fire coin is copied accurately
secondly, if there is any problem with the correct address, please contact the customer service of btoex platform and ask them to see what the problem is. Generally speaking, the customer service will help solve it quickly
finally, try to play on large platforms, because there are too many problems on small platforms.

8. 1. First of all, you need to know the concepts of public key and private key (you don't need to read this part already)
public key and private key are terms in asymmetric encryption of modern cryptography. They usually encrypt information with public key and decrypt information with private key. Why? Because when you watch TV dramas, telegrams are encrypted symmetrically. The disadvantages of this encryption method are obvious. If someone knows the key and encryption method, they can decrypt the telegrams according to the encryption method. Until asymmetric encryption, the situation has changed. Public key is the key that can be made public all over the world. For example, when you communicate with Google, you encrypt with the 1024 bit public key given by Google and send it to Google. Only he has the corresponding private key, and only he can decrypt it, so the communication security is ensured
2. Bitcoin mainly uses ECDSA, which is the elliptic curve signature algorithm, This algorithm has two characteristics. Note that these two points are very important to the following
A. as long as you know the private key, you can calculate the corresponding public key
B. If you have signed something with the private key, you can use the public key to calculate whether you signed it or not
3. After knowledge preparation, let's start with the transaction of bitcoin. In fact, bitcoin has no wallet, only transaction bills, and the whole bitcoin is a lot of transaction bills
for example:
bill 1 transfers from a to B to XXX bitcoin
Bill 2 transfers from B to C and D to XXX bitcoin
bill 3 transfers from C to e to XXX bitcoin
.... Anyone who downloads the client can receive all the bills from the day when bitcoin was established, so as long as all the bills are downloaded, they will naturally know how much money should be left on each account (think carefully here)
4. The account of bitcoin is the public key mentioned just now
5, Here is the core part!!! Each bill is a piece of data. After you sign it, it will be sent to the whole network, and the data structure will be reversed into easy to understand Chinese. The explanation is as follows:
from (who sent it, including two parts)
previous TX: the ID of the bill for which you want to spend the money, that is to say, any money you spend should have been transferred to you, You need to show the ID of the bill
scriptsig: your signature for this transaction is to hash the bill with your private key, only you can do this hash
to (who accepts, including two parts)
value: how much to send
scriptpubkey: the public key of the other party, and the bitcoin account is a public key
6, How to send it? Bitcoin communication is not so complicated. You can compare it to IRC channel, but different from ordinary "IRC", any client is an "IRC" server. When you start the client, you will receive the client address with public IP around, that is, the "server" list. This list is constantly refreshed, and it is all other bitcoin users, So when you shout a word in this "IRC", people around you will hear it and spread it all over the world
7. After sending the signature to the whole world, all the clients who receive this list will verify whether your signature is correct, whether you sent it, and whether you have so much money (according to the historical transaction, you can calculate how much money you have to spend)
if you have calculated this transaction, it's OK, Basically, the transfer is successful
8. In fact, the other party has accepted bitcoin, but in order to spend it, he must have the private key corresponding to the address (public key). So he can fill in the from header of a form. Previous TX is the serial number of the transaction just now. Scriptsig fills in the hash signed with his private key...

9. The number of people who enter the bitcoin website is large, so it's time to get stuck. Just ask the customer service carefully. Now the customer service reply is a little slow, because there is a platform that needs to use bitcoin for transactions, so it will be a little slow to buy coins in bitcoin China. We can analyze the future trend of bitcoin for you.
