Remember that it easy to show 2x-5x profit in chart after pump.. But truth is 90% chart analyst not able to make those profit n few discipline experts book profit each level with a target.
Dont enter in FOMO in this Alt cycle, u will be REKT like 2018.
Although your suggestion is good and FOMO is never a good thing as you either get bull trapped or you have to face loss in most cases but also remember the other side of the story that a good alt season is long due and i think it can easily be expected in 2021 if we consider historic market cycles, so do not panic with your quality alts they will definitely give you good profit as a result of bull season.
