I have question Do the beginners go for Future trades or with slow spot trading

I have probably made about 30 million in total from trading cryptocurrencies, with a principal of less than 200,000. I haven't worked for seven years and have been trading cryptocurrencies full-time. I have experienced many ups and downs in the meantime and hope to share more of my experiences with everyone, from which you can learn useful strategies for yourself:
1. The risk of each trade must never exceed 10% of the trading principal, that is, 10% of the trading principal. It is recommended for beginners to keep it between 2%-5%!
2. After entering the market, you must never blindly close positions due to a lack of patience. Market fluctuations take time; before the market proves that your operation is wrong, you must have enough confidence and patience.
3. You must execute according to the plan and never overtrade.
4. After a correct trade that has made a profit, use the method of adjusting stop-loss and take-profit as a safeguard, and boldly strive for even greater profits until the trend changes.
5. After entering the market, you must not casually cancel stop-loss points. The entire trading process after you enter the market is a process of risk control, so you must set up protection after entering, and it is strictly forbidden to trade without protection.
6. Avoid adding costs after a successful trade, that is, avoid adding positions.
7. You cannot casually switch from a long position to a short position; this is a high-skill operation.
8. When buying and selling becomes smooth, you must avoid casually increasing your position, as the probability of making mistakes is very high at this time because you may become complacent.
