1. First, only buy Bitcoin and Ethereum. Other currencies fluctuate greatly, which will bring you great psychological pressure. Bitcoin and Ethereum will also fall by 20% in one day.
2. Try not to buy in small exchanges. If there are no coins in Ouyi and Mouan, it is probably a very risky coin. No matter how the person who asks you to buy it tempts you, don't go. If you really have to go, you can ask me first.
3. Don't go all in at once. You must manage your positions well. Even in a bull market, there are many opportunities to pick you up.
4. Don't play contracts. Contracts are a tool for risk hedging, not a tool for gambling.
5. Don't transfer coins casually. There is no need to withdraw coins to your wallet after buying thousands of yuan. The probability of a novice losing it is much greater than the probability of being stolen.
