Right everyone is a genius in a bull market, but when it crashes a lot of traders realize that they may not be as genius in trading as they thought they are.
It's to become delusional when things go right anyway and you are part of a bull market.
the case will be different for each asset held. market conditions and each person's psychology also differ in responding to market conditions.
sometimes withholding assets for the long term is sure to stress people out. especially if market conditions are in a downtrend which makes our asset value decrease continuously.
but for several potential projects. hold assets within the first 3-5 years the platform is running I don't think it will cost us any losses.
such as BNB which continues to strengthen every year. and some are creating their new ATH. that's all because Binance is a good project with a lot of development.
but if you see what happened to a bad project that even their team had left behind, it will not make us profit if we hold assets for a long time.
Take Bitcoin as an example: if you bought Bitcoin in 2016 and didn't sell in late 2017, you went through a mental breakdown. But now you would be more than happy about your decision. You may think if you sold you could have rebought more, but that's too much of a good thing.
Holding long-term is a commitment to your understanding of the asset and the effort you put in to get to acquire what you believe to be knowledge. Downswings and upswings should be part of your calculations right from the beginning.
