I agree with your thoughts on this. Emotions are one of the most important factors that affect decision making. But emotions should not get over us. A good investor should be able to control his emotions for earning profits in the long run, as there are many ups and downs in the value of cryptocurrency. So what one can do is avoid checking the prices again and again, especially when the market is low.
Yes handling their emotions is the biggest issue many traders or retail investors have, especially at the beginning.
You can have read several books, know all the theory, but if can not be cool when it is needed you will very likely screw up your trade or investment.
That's the main reason why so many sell at the bottom or buy the top.
Often you have to do the exact opposite of what the majority is doing or thinking.
Buy when the majority of market participants is crying and sell when this majority is thinking about to get their first Lambos.
In theory, it sounds simple but tell me why so many people are losing money. It is very difficult to deal with emotions. It seems to me that now the market is frozen in an emotional confrontation. Those who panicked have already sold the coins. There were only the most persistent. It's funny, but those who panicked at first won.
