Bitcoin private key may be the same
the private key is like your bank card password
the address of bitcoin wallet is like your bank card
as long as you have the bank card and password, anyone can withdraw money from ATM
the address of bitcoin wallet is public, which means that everyone else has your bank card, so your bank card password (private key) becomes very important at this time
once your key is disclosed, others can transfer your bitcoin

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
1. Who benefits the most from researching and hyping bitcoin
2. In essence, it's USA's Intel, NVIDIA, amd + ATI
3. Bitcoin requires a huge amount of CPU, GPU, memory, motherboard, power supply, wire and venue
4. Since the speculation of bitcoin, the sales of CPU, GPU, memory, motherboard, power supply and wire are the highest
5. It's the CPU and GPU instry of USA that really make a big profit, while the retail and service of other countries are just middlemen making a difference
6. The plan to hype bitcoin: it boosts the high-end, core and basic chip instry capacity of USA. other countries are compradors
7. Harm: lose the ability to develop domestic high-end, core and basic chips, and become a retailer that can only sell chips for USA.
