I think this situation is from the category, and why I did not buy Bitcoin 5 years ago. I sold tokens myself earlier than necessary, and then they grew even more. In such a situation, you just need to use intuition, market analysis and token behavior, read news, chat project. Comprehensive analysis, but no one is immune from such errors. You just need to keep those tokens you believe in longer and not sell them for a minimum profit. Just catch the moment, often there is a sharp increase in the chart 100-200 %, at this point you can sell.
