When I first started in the industry, I saw BTC rise sharply from 22,000 → 24,000 USD within a few hours. Continuous green candles, the feeling of FOMO arose: “If I don't get in now, I'll definitely miss the opportunity!”
I decided to invest all 100% of my capital without any plan. The result a few hours later: the price reversed due to bad news from the US market, BTC plummeted to 23,000 USD, and my account immediately lost 10%.
