Will the input key of BTC be recorded

1. This is the order of importance: BTC private key, wallet security password, BTC address
the private key is everything and must not be told to anyone
as long as there is a private key, you can re import the wallet and reset the wallet security password
a BTC account can have many addresses, so the least important one is the address. No matter how unimportant, you can't just tell others.

2. Each person's wallet has more than one bitcoin address, and each bitcoin address represents a certain number of bitcoins. The bitcoin address is generated through a public key hash (rpiemd + Sha), and the public key is generated by the private key through elliptic curve (ECC). The private key is kept in the bitcoin wallet and should not be disclosed. The public key, together with the bitcoin address, needs to be publicly released through transaction records ring payment transactions, and the effectiveness of payment transactions is verified by the blockchain system.

3. You can install a computer manager on the computer
and then open the toolbox to see a file decryption function
after using this function, the encrypted computer files can be automatically released

5. No, there are several reasons why bitcoin was stolen
1. A stolen bitcoin can't be retrieved, and if it's lost, it's lost.
2. Bitcoin has transaction records, but the address is hidden, and you can't find an indivial.
3. Every bitcoin has a key, and only if you have this key can you be admitted to own bitcoin. However, if bitcoin is stolen or lost, your bitcoin will disappear completely
therefore, the theft of bitcoin does not belong to cracking, it may be e to internal personnel.

6. It's hard to find this. It's better to change to a better exchange, such as bitoffer

7. Because a lot of custody in the trading platform is not extracted, if the trading platform has an insider, it is easy to be stolen. If you extract it from your own computer, there won't be such a thing.

8. Using public WiFi payment, if the password is encrypted in the app used for payment, then your password will not be stolen. If the app is not encrypted, the risk of password leakage is very high. Generally speaking, WeChat payment, Alipay, UnionPay cloud flash payment, mobile phone banking and so on, these APP used for payment will do well in password encryption.
