That night, I exploded a contract and bought the dip at 3900 Bitcoin. By eight o'clock the next morning, I had already broken even. Unfortunately, when BTC surged and then dropped back to over 5000, I knew in my heart that this was the bottom, but looking at the charts, news, and technical indicators, I felt there was a high chance it would drop to the 4000s, so I thought about making a trade. As a result, I sold at the bottom, and until now it has reached 120,000 BTC. The biggest lesson for me is: don't easily make trades; it's like picking up sesame seeds and losing watermelons.
