1. Do not trust the so-called signal teachers in the square; 95% of them are here to cut your rebates. They will make profit charts look very appealing to hook you in. If you insist on going in, at most take 10% of your position to follow, because there is a high probability that it will go to zero.
2. When trading contracts, always set a stop-loss for each position. Create a trading plan and test your trading plan over 100 times or more in the K-line replay function, recording your profits and loss ratios. Finally, calculate whether your expected value is positive. Do not rush to close positions with floating profits, and strictly enforce stop-loss on floating losses, sticking to your trading plan.
3. In the cryptocurrency circle, there is also a category of paid influencers who charge a monthly fee to pull you into groups for trading signals. The quality varies; some are exceptionally good, while others are purely for cutting profits. Before joining, do not be fooled by their rhetoric and profit screenshots. Inquire and search thoroughly before joining.
