It's been three months since I started trading contracts, and I have lost 3000 overall. This month has been profitable, and I can basically determine the major direction, but it's quite ridiculous without a bottom or a peak. For Bitcoin, I went long from 86000 to 91000, and then shorted at 91000 and got liquidated. I knew it would rise, but this increase exceeded my understanding. The news is also paying attention, spot trading volume is being monitored, and patterns are being studied, so setting a stop-loss is the most important thing. In the subsequent event contracts, I lost 2 out of 14. I really couldn't take it anymore and went to play event contracts, where making money is a low-probability event. Patience and stop-loss are both essential.
