Unlike the private key of Bitcoin, the loss of Bitcoin will not be caused by information leakage, so you can safely tell anyone the address of Bitcoin.
Through the blockchain browser, you can view all the transfer transaction records of each bitcoin address.
Commonly used bitcoin blockchain browsers are:

There are four commonly used bitcoin address formats.
1, BASE58 format
BASE58 format is a common bitcoin address format, which generally starts with 1.
For example:1M8dpubqxsvunnnixw5 of rciguxctwpud
2.HASH 160 format
HASH 160 format is the result of calculating SHA256 signature of 130-bit public key by RIPEMD 160 algorithm.
Example: fbfbfb58defc272942fc31d00c007b 59a a4cb5087a.
3.WIF compression format
WIF compression format, namely wallet input format, is the result of compressing BASE58 format. It is a 130-bit public key format, and it is the most primitive bitcoin public key calculated by ECDSA algorithm.
For example:
0469 b 0e 479 c 9 a 358908 db 9 cf 4628 BDD 643 C3 f 8 1 c4f 0096 ad 442 da 6 ca 8 BC C4 FD 86 A8 d47 d 7 a 865 e 1 78 b 6d 062 CCC 9 b 702908973952062 a 1d 767 da 9 B2 BD 2095 D5 CCF 6 e
4.60-bit public key format
The 60-bit public key format, namely 130-bit public key, is the result of compression.
For example:
0269 b 0e 479 c 9 a 358908 db 9 cf 4628 BDD 643 C3 f 8 1 c4f 0096 ad 442 da 6 ca 8 BC C4 FD 86
Bitcoin is based on mathematical cryptography, and Satoshi Nakamoto uses Elliptic Cryptography (ECDSA) to generate the private key and public key of Bitcoin.
The public key can be calculated from the private key, and the value of the public key will get the bitcoin address through a series of digital signature operations.
Bitcoin addresses are randomly generated by algorithms, so some people will ask, since they are all randomly generated, will bitcoin addresses be duplicated? Of course, there is no need to worry about this problem.
Because the length of the private key of Bitcoin is a 256-bit binary string, the probability that two randomly generated private keys are completely duplicated is one of 2 256 ≈10 77, which is so big that you can't imagine it at all, and it is much smaller than the probability of winning the lottery. So don't worry, everyone's bitcoin address is unique.
