1. I'll give you my address (address). You can find my zip code (public key). You can write to me with my zip code (public key) + address. The mail will be sent to my mail cabinet. I'll open the mail cabinet (private key) with the key I have. The key of express cabinet is stored in my wallet (wallet)
1. The mail cabinet is stolen (the database is stolen)
2. The key is stolen (the private key is stolen)
3. Knowing my home address (the public key is stolen), the lock of the mail cabinet is opened violently (the private key is cracked violently).

2. The private key is your bank card password, and the address is your bank account number, but the private key is more important. With the private key, you can push out the address. If you forget the private key, you will lose everything. The signature is personalization, plus a verification procere. The wallet is a small ATM, which can be sent after the update. If the wallet file is saved, it will be OK. BTC China is OK, and you can buy money.
3. Public private key is peer-to-peer encryption. You can see RSA encryption
only the private key can decrypt the content encrypted by the private key
only the public key can decrypt the content encrypted by the private key
here, the public key is your bitcoin ID, and the private key is your wallet
when using bitcoin, you should take care of your wallet, and you'd better encrypt it with a password, You can use your bitcoin
there are many bitcoin trading platforms on the Internet, and you can find a lot of them by Google search
generally, you need to mine bitcoin, and there are also mining platforms on the Internet, but now the income is low, and the display card is burned

4. The digital signature of bitcoin is an anti-counterfeiting string generated only by the transferor of bitcoin transfer. By verifying the digital string, on the one hand, it proves that the transaction is initiated by the transferor, on the other hand, it proves that the transaction information has not been changed in the transmission
digital signature shortens transaction information to a fixed length string through digital digest technology. For example, when Niuniu initiates a bitcoin transfer, it needs to first digest the transaction into a string, and then encrypt the digest with its own private key to form a digital signature. After the completion, Niuniu needs to broadcast the original (transaction information) and digital signature to the miner, and the miner uses Niuniu's public key for verification. If the verification is successful, it means that the transaction is indeed sent by Niuniu, and the information has not been changed
at the same time, the private key encrypted by digital signature is inconsistent with the public key decrypted by digital signature, so asymmetric encryption technology is adopted. It looks so complicated. In fact, you only need to input the private key to complete the transfer instantly!

5. The digital signature in bitcoin is generated by the initiator in the transaction. In order to ensure that this transaction is initiated by this person, and the data is not tampered with ring transmission. Digital signature is simply a complete transaction information, compressed into a fixed format string by digital digest technology, and then generated a private key by asymmetric encryption technology. The complete transaction information and digital signature are sent to the miner. The miner decrypts the digital signature with the public key of the transaction initiator. If the decryption is successful, the transaction data will be written into the block.

7. If you don't understand BTC at all, I'll tell you nothing about it.
according to the current price and difficulty increase of mining machinery,
none of the mining machinery can recover the cost, all of them are loss goods.

8. I've also had this problem. The main thing is to write the correct wallet address in the address bar What I met is that the address bar can't be pasted), so I have to input it one by one manually. More than 30 letters, including case and number, should be 100% correct. I think it's the same thing.
