Lost $400,000 in a day, but didn't go to extremes—this might be the most impactful experience I've had in my cryptocurrency trading career. Honestly, before entering this market, no one would insure you. The volatility in the crypto space is just like that—one leverage boost, one black swan event, and your account can go from green to red. After experiencing losses of this magnitude, you either break down or learn to accept the market's brutality. I chose the latter. The key is mindset—losses have already happened, but being able to come out alive and continue is a victory in itself. Many people become impatient with small gains and desperate with small losses; in fact, psychological resilience is more valuable than trading skills in this market. I hope my experience can help other traders understand how important risk management and mental toughness are in crypto asset trading.
