『One』Is Bitcoin and other digital currency wallets really safe?

There are so many digital currency wallets on the market at present, it is recommended to choose a relatively well-known and official wallet, which is relatively safe. For example: Bitpie Wallet, Huobi, Binance, etc. However, these apps cannot be downloaded at present, and you need to log in to the App Store with a foreign account to search them.

『II』How to choose the best bitcoin cash wallet

It is recommended to choose some well-known ones, such as electron cash (recommended by currency circles is the best one to use) BCH wallet), bitcoin.com (the wallet name is called this), BTC wallet and Bitpie are all domestic, and those with poor English can choose.

“Three” Bitcoin Wallet

Bitcoin was born in a paper in 2008.
A man named Satoshi Nakamoto came up with a revolutionary idea: let’s create a currency that is not controlled by the government or anyone else! This idea is crazy: a string of numbers, backed by no assets and no one responsible, you pay it as money, how can anyone accept it?
Merkle tree
It looks very similar to a binary tree, but this is the hash value of the following two nodes to get the upper node. Only need to remember the root node, you can detect whether the whole tree has been tampered with.
The root hash value is stored in the block header, and the transaction process is stored in the block body. Full nodes include block header and block body, but light nodes (such as Bitcoin wallets on mobile phones) only include block headers. This tree can prove to contain a transaction that has been written into the blockchain.
3. Consensus protocol
Two issues that 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 for digital currencies.
Transactions in Bitcoin must have input and output, where the coins come from and where they go.
Under normal circumstances, there may also be two forks, because two nodes obtain the accounting right at the same time, and the block packaged by the two nodes calculates the random number at the same time. At this time, two forks will temporarily coexist, until one of the blocks finds the next block first, which becomes the longest legal chain, and the other fork is discarded.

Sybil attack
A malicious node keeps generating accounts, and if the total number of accounts exceeds half of the total accounts, it will gain control of the blockchain.

Consensus in Bitcoin
Some nodes are malicious, most nodes are good.

Idea 1: Pack some transactions into blocks as candidate blocks, let each block vote, and write it into the blockchain if it passes.

No, because some malicious nodes keep publishing blocks containing malicious transactions, they keep voting and occupying resources. And some nodes do not vote.

Idea 2: Instead of voting by the number of accounts, vote by computing power. Each node can generate legal transactions into the block, and these nodes start to try random numbers until H (block header) ≤ target is found, then this node has the right to bookkeeping.

The only way to generate bitcoin
coinbase transaction. This does not need to point out the source of the coin, the node with the accounting right (find the random number) will have a block reward.

50BTC->25BTC->12.5BTC, every 210,000 bitcoins, the reward will be halved.

The process of bitcoin competing for the right to bookkeeping is called mining. The nodes that compete for the accounting rights are called miners.

『4』Which bitcoin wallet do you usually use?

I trust the Bixin wallet. I have been buying and selling bitcoin on it since 2017. It’s done very well, there has never been a problem, and there are many types of digital currencies to choose from.

『Wu』What is the difference between a bitcoin exchange and a bitcoin wallet

Bitcoin is an electronic currency, digital currency, generated by open source P2P software. An online virtual currency. Bitcoin is also paraphrased as “bit gold”. Abbreviation: BTC.
Bitcoin is not issued by a specific currency institution. It is generated by a large amount of calculation of a specific algorithm. The Bitcoin economy uses a distributed database composed of many nodes in the entire P2P network to confirm and record all transaction behaviors. The decentralized nature of P2P and the algorithm itself can ensure that the value of the currency cannot be artificially manipulated by mass-producing Bitcoin.
Bitcoin is very similar to cash
The benefits of Bitcoin are: no freezing, no tracking, no tax, extremely low transaction costs. Compared with people who speculate in coins, it is wealth, and people outside the currency circle may think it is a scam.
Bitcoin is a relatively mainstream digital currency. It can be properly invested, and transactions are risky. Invest prudently. You can�Search for bitcoins on Huobi, Binance, OK, Dobi trading platforms, etc. These are relatively large trading platforms, invest in mainstream digital currencies, do not invest in altcoins or air coins.
Bit exchange can trade all kinds of digital currencies, and the bitcoin wallet can only store bitcoins
