The mistakes that you had usually belong to the Bitcoin Discussion section, this thread is in the Trading Discussion section. Btw, I've made fatal mistakes in crypto trading. In 2020-2021, I made a very good profit by holding Bitcoin and then decided to start trading. Luckily, I made a huge profit from trading but that was mostly caused by the bull market because during bull run, everything rises, so you can't make a mistake until the bear market hits. My biggest mistake was playing with Futures Trading with increased leverage. I was spending days in trading to make a decent profit. Once, I spent 2 days and nights in a row in trading, made a very decent profit and then I decided to open one last position on QTUM token to achieve my goal and then I'd sleep. Sadly, I accidentally opened a position with 20x leverage, which made me go bankrupt within minutes and I couldn't close the position because I accidentally fell asleep. I woke up with Binance SMSs reporting that I got liquidated. That was the terrible day of my life.
