You could have sold it last year when bitcoin had reached its ATH twice. Definitely, not today since all your efforts from hodling will be totally gone, better keep on buying this time while there is good opportunity to buy. However, if you're not still in need of fiat or don't have any urgent needs, so what's the use of selling? You can generate more profits if you can hodl them for a longer time since bitcoin gives a new peak every year, much higher than the last years ATH.
