1. Basically, it's OK to choose a few top ranked wallets. You can take a look at the celletf platform.
2.
I use my wallet, of course
this is the wallet interface
3. If it's only a small amount, it's recommended to put it directly in a safe and well-known wallet. You can withdraw the currency when you use it. For example, I have been using the coin bag, the bitcoin wallet, to confirm the withdrawal of coins in seconds. Transaction fees are also low.
4. Bitcoin was born in a paper in 2008
a person signed by Nakamoto Tsui has put forward a revolutionary idea: let's create a currency that is not controlled by the government or anyone else! This idea is crazy: there is no asset support behind a string of figures, and no one is responsible for it. How can anyone accept it when you pay it to the other party as money
Merkle tree
looks like a binary tree, but this is the lower two nodes. Take the hash value to get the upper node. Just remember the root node to detect whether the whole tree has been tampered
the root hash value is stored in the block header, and the transaction process is stored in the block body. All nodes include block header and block body, but light nodes (such as bitcoin wallets on mobile phones) only include block header. This tree can prove that a transaction has been written into the blockchain
3. Consensus agreement
two issues should be paid attention to in decentralized currency:
1. Who can issue digital currency: mining
2. How to verify the legitimacy of transactions: blockchain
double spending attack
double spending attack is a major challenge of digital currency
all transactions in bitcoin have input and output. Where does bitcoin come from and where does it go
under normal circumstances, there may be two bifurcations, because two nodes obtain the bookkeeping right at the same time, and the two nodes package the block and calculate the random number at the same time. At this time, the two bifurcations will coexist temporarily until one of the blocks finds the next block first, which becomes the longest legal chain, and the other one is discarded<
Sybil attack
a malicious node keeps generating accounts. If the total number of accounts exceeds half of the total accounts, it obtains the control of the blockchain
consensus protocol in bitcoin
some nodes are malicious, and most nodes are good
idea 1: pack some transactions into blocks as candidate blocks, let each block vote, and write them into the blockchain if they pass
No, because some malicious nodes have been publishing blocks containing malicious transactions, and they have been voting and occupying resources. And some nodes don't vote<
idea 2: vote not by the number of accounts, but by computing power. Each node can generate legal transactions and put them into the block. These nodes start to try random numbers until H (block header) ≤ target is found, then this node has the right to account
the only way to generate bitcoin
coinbase transaction. There is no need to point out the source of the currency. If you have the bookkeeping right, you will get a reward< br />
50BTC-> 25BTC-> 12.5btc, the reward will be halved for every 210000 bitcoins
the process of bitcoin competing for bookkeeping rights is called mining. The node competing for bookkeeping right is called miner.

5. The essence of BTC is a distributed, algorithm-based and public network account book (just as the essence of a bank is a private account book which is not publicly controlled by the central government). The wallet (private key) is actually the right for you to modify the account number (public key or bitcoin address) in the account book. The wallet corresponds to the account number. In fact, the specific wallet file contains more than one private key information, which can be copied to other places for use. As long as you have the private key corresponding to the account, it's like having the password of the bank card. Understand the above, you should also understand the answer to your question - B has 10btc on the address. It's not about the computer. This may be better understood by you: wallet = private key (bank card password) + public key (bank card number) BTC network system = Bank, access to BTC network with wallet = bank card inserted into ATM and certified, payment = transfer to other accounts.

7. How to choose BTC wallet and how to store your bitcoin? This is an important problem that every bitcoin user must face. Bitcoin gives you more freedom and power to control your money. But if you are not careful, it may bring disastrous losses. If you choose to remain in complete control of your bitcoin on your own, then there is no one who can stop you from doing something stupid and pay for your mistakes. There is no bitcoin company to call and try to convince your legitimate owner of your address so they can give you the key back. However, there are friendly and secure services based on bitcoin, or intermediate solutions, which can let users avoid the risk of operating wallets.
