PC client BTC

1. from http://www.taobtc.net/ The wallet file of bitcoin QT client is wallet.dat, and the wallet file of multibit client is multibit.wallet. The file name, size and format of these two files are not the same, so how to switch? If you don't need to save the original address, it's the most convenient way to send the coin directly to the multibit address. If you need to keep the original address, you can export and import the private key. The details are as follows: 1. Open bitcoin QT client, find the address where you save money (you may have multiple addresses, find the one with money), right-click - ; 2. Open help debug window console in turn, input the command mpprivkey (space), paste the address just copied, and press enter; 3. Now you should be able to see your private key. It is a string of 52 characters, copied down; 4. Open multibit, assuming you have no money in it, select tool export private key, select path, select no encryption, and click export private key; 5. Use Notepad to open the. Key file that you just exported, which contains the private key that you just exported (the line that starts with #) is the comment). Change the private key to the one you just copied, and you can leave it at any time later. Save it and exit; 6. Click Tools - Import private key, select the. Key file modified just now and import it; 7. After a short update, you should be able to see the original address of the import and your balance in the original address. Remind: 1. Do not disclose your private key, know the private key can control the corresponding address of bitcoin! 2. Other clients, such as electric and armory, can import and export in a similar way, but the format of private key is 51 bit and 52 bit, which may not be universal.

2. One is stored in your computer hard disk, the other is stored in the mine pool account, so it's different

3. 1. It's very difficult for an ordinary home computer to find a BTC. It took 30-50 years or even longer to find one according to the current situation. So people who know computers won't be so stupid. 2. To dig BTC, you must have a special mining client. There are only a few in the world. Search online. Then look at the task manager on your computer to see if there are abnormal programs running, and then compare the mining client program to determine whether there are BTC programs running on your computer. Basic attention to BT BTC BTC word program can be adopted

4. If you want to contribute to the bitcoin network, it's a good choice to run a full node to synchronize the block data; If you just want to use bitcoin, you don't need a full node wallet at all. You just need to install a new wallet. The better one in China is the coin pack.

5. It depends on your configuration. Ordinary computers can dig, but I don't know how long it will take to dig one

6. Bitcoin has collapsed. It's a Ponzi scheme. You can't earn money from mining and electricity bills these days.

7. Your questions are a bit confusing
according to the bitcoin address, you can find out which exchange generated it
the query website can't be written down here. It's known that it's blocked.

8. Let's do it together. First, close the official bitcoin client. In the main interface, select file → exit
open the windows start menu
if you are Windows XP, select "run" and enter the following contents: Explorer% appdata% & # 92; Bitcoin if you are Windows Vista or windows 7, directly enter: Explorer% appdata% &# 92 in the "search programs and files" box of the start menu; Bitcoinwindows Explorer opens. You only need to the wallet.dat file to other hard disk partition, mobile hard disk or U disk to complete the backup.

9. The wallet address represents your different wallet. After the computer reloads the program, it will automatically generate a new wallet address. Of course, it is different every time. If you only want to use one wallet, you just need to export your wallet address. Next time you reload the system or the wallet program (or install it on other computers), you can import the address or create a new address manually

good luck!!!
