How to actually take profits?

You know, while everyone is shitting their pants about all the news we got recently I actually want to prepare myself for the next bull run. Holding crypto is great and all but if I actually want to do something with it I have to sell it. As we can see the market ain’t amazing but as we all know sooner or later we will most likely have a time where crypto surges upwards again.

Now my issue is how am I supposed to take profits without feeling shit afterwards. Selling could go 2 ways, first it could go down after you sold and you would feel like a genius, or second it only goes higher and higher after you sold and you feel like shit because you could of “waited”.

Whats the best way to approach this?
