It's better to keep holding, and maybe you can use the current conditions to buy, but if you think about selling, then I don't think right now is the right time.
You're right for your observation, holding up your stash in the face of bearishly cryptocurrency market is a positive type for everyone who believed on the said technology (Bitcoin). But wit an exception of this categories of people in the world: those who actually need these funds to attend to more important needs or pressing needs of their homes. There was a case of someone who needed an urgent need during the recent lockdown and decided to sell out, this is understandable. As for me, am holding up the needed available stash for my future use.
