A few points to emphasize
1. Emphasize: It is best for novices not to engage in contract trading;
2. It is recommended to make 90-95% of spot and 5-10% of contract;
3. For spot, it is recommended to build positions in batches, and you can buy the bottom several times to reduce costs;
4. If you operate contracts, the initial position plus the replenishment position should not exceed 10% of the total position to control the risk of forced liquidation and protect the principal. $BTC
