How to open BTC backup Wallet

1.

The private key of bitcoin wallet cannot be viewed online. Bitcoin exists on the platform. To download core or classic is the real wallet, and then you can view it

[description of private key of bitcoin wallet]:

1. Wallet encryption refers to automatically encrypting and storing the wallet with private key. The official bitcoin client supports wallet encryption since version 0.4.0. The encrypted wallet will prompt you to enter your password every time you pay. If the password is wrong, the client will refuse to pay

2. If you replace it with the earliest backup wallet (wallet. DAT), you can still trade normally. Considering the principle of bitcoin, it can be concluded that as long as there is a private key (wallet), you can prove that you are the legitimate owner of the wallet. No matter whether you encrypt or delete the wallet (the core is the private key corresponding to an address), you can't deny it

3. When backing up the bitcoin wallet, you should also pay attention to the existence of bitcoin payment change mechanism (for example, if you send 50 BTC in a complete 100 BTC to an address, the system will send 50 BTC to the other party's address, and return 50 BTC to a new address of your client, which will not be directly displayed in your address list)

4. After sending bitcoin to other addresses 100 times or using 100 different addresses to receive bitcoin, please back up your wallet again, otherwise the returned and received bitcoin will be lost forever. In addition to encrypting wallets, users can also generate offline paper wallets and brain wallets

2. Bitcoin core is an official client used to manage the private key of bitcoin. Having the private key of the bitcoin address means having the control right of the corresponding bitcoin. Once the private key is lost, it cannot be recovered. Therefore, it is very important to back up the wallet
the wallet file of the wallet client is the database for storing the private key of bitcoin. Both the private key and the public key are stored in the wallet.dat file of the bitcoin wallet. Keeping wallet files securely in multiple locations prevents bitcoin from being recovered in the event of an accident
wallet file location
Windows XP - C: & # 92; Documents and Settings\{ username}\ Application Data\ Bitcoin\ wallet.dat
Windows 7/8 - C:\ Users\{ username}\ AppData\ Roaming\ Bitcoin\ Wallet. Dat
Mac OS X ~ / library / Application Support / bitcoin / wallet. Dat
linux ~ /. Bitcoin / wallet. Dat
the above is the default wallet directory of bitcoin core client. If the data directory is specially set, you can search the keyword "wallet. Dat" through windows to the wallet. Dat

the performance output of the graphics card is powerful, which can be competent for all kinds of large-scale stand-alone games and 3D games, and the replacement improves the level of game experience

5. Yes, as long as you back it up. Bitcoin backup is very important. If you don't back it up, if something goes wrong with your computer or mobile phone, your bitcoin will probably not be found. However, I don't recommend that you download the bitcoin client wallet. It's too cumbersome and unsafe. Now online bitcoin technology is quite mature, and you can use online wallet.
