I would say cash out if you would, since you already have these fears, but leave a starters buy-in in the strongest soil. You never would know what may come up. So allow the amount that wouldn't get at you much for a loss if the worse happens. You are at no loss at much if it's a little. You only have your finger to bite in regret when you see others in their days of happy hour. Moreover, consider such giant individuals, companies and some economies that have taken big leaps into crypto. You wouldn't be losing as much as they, if it all finally comes crashing. But I very much doubt that, cos if you look at how this field has made a lot of "nothings"  sizable giants and wise, you wouldn't mind being one too, would you?
Stick around if you could.
