Most times it is always good to wait for those FOMO periods and then gradually start offloading and then at least, once you see you have been able to get out your initial capital, then, you can decide to start playing with the rest until you are sure the market is switching back to a downtrend and then you can get out completely.
I am a trend follower anyway, and I do not like trading a pump and dump market, which makes it for me to always be able to trade the trends on any time frame without having to offload bit by bit on the way up. When I need to get out, I get out and when I need to get in, I do so which includes stopping losses as well.
