Bitcoin old address still works

1. Should be all right, should be an invalid address, so it is an unconfirmed transaction ah! No deal.
2. The owner of the building is energetic and seems to be able to do a counter experiment; Don't connect the computer to the Internet. Take a wallet from an external USB flash drive and put it in to see if it can show how much money there is? In fact, the experiment in front of you should not be that the wallet can automatically generate a new address without networking, but that there are a large number of hidden change old addresses of your own in it. However, a large number of hidden change old addresses should be in the wallet.dat file, not in the empty wallet terminal software.
3. 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 />

4. It's simple and convenient to make money, and the income is very good, which can be considered.
5. It can be split, and one becomes 1000W
6. Now it seems that bitcoin is not as popular as it used to be. It's also very devalued. It seems that no one has bought it. People who have made a fortune because of a few bitcoins seem to have disappeared now.
7. If you are cheated, you can call the police, if not, you can't find it back. If you transfer to a wrong address, then this bitcoin will disappear. Bitcoin transfer is irreversible
8. It should be said that bitcoin is a virtual currency. It has no issuing authority, unlike conventional currency, which has the authority and credit guarantee of the bank. Moreover, the value of bitcoin fluctuates greatly. Even if it is held for a long time, it can not guarantee that the value in the future will be higher than that in the present.
9. It needs professional miner.
