I have seen many people who are very good at trading but still make these mistakes. When the price of Bitcoin goes up they get frustrated and make the wrong decision is a tendency that works in many people at different times. There seem to be many of us who give advice to others. But when we open a trade we cannot control our emotions. Because we forget that we should control our emotions.
You are right, I have been in this situation, but one thing I have controlled, and that is to control my excitement and to keep patience. I have seen my overall portfolio with more than $500 loss and controlling my emotions like nothing happened, and to recover that balance but still did not book a penny because I have plans and stuck to them.
The main reason should be, that you have to choose a better coin to invest in like ETH BTC, or AVAX, or whatever other coin, investing funds only in BTC is always profitable. But doing future trade is what makes most people paranoid and doubtful and they are unable to control their emotions, no matter how expert they are, so that's why I have left future trading.
