Patience is always the key when investing. If you FOMO in there is a high chance you'll just lose money. Wait for the right time when investing and control your emotion. Market won't go up forever and eventually it will go down. If you fomo in you'll be forced to make it long term investment to not lose money.
Yeah, it's actually called the sportsmanship spirit kinda feeling we need to keep with Bitcoin investments. That's because, those who bought at $20k are still holding (I'm talking about retail investors) whereas weak hands have sold off theirs. This shows that they believe in the future of BTC and are waiting for the right time. It is true that there will be a loser for every winner and there needs to be one, because without a loser how can there be a winner? You can't sell if nobody is buying and if people are buying it, it means the hype is working out so just chill and let it work - this is all I told him the last moment when he wanted to hodl deeply but sold (obviously, without asking me) and even I didn't get a feeling that he's going to commit suicidal mistake towards his capital while trying to tabulate things to a better level but actually ruined it for himself (at least saved his Dad's money).
He committed a mistake? He became a loser and it was his choice to be one. He didn't wait.
I salute to those who didn't sell a cent worth of BTC during the doom of 2018-19, a bigger salute to those who had the chance to get on the train very early during 2009-10 and are still one of the early hodlers. They're the definition of patience and motivate us to follow them and hodl at least till it reaches back our purchase value.
