Basic principle that everybody always been taught but hardly implement "Don't invest you dont want to lose in Crypto" a simple but powerful, if you afford to lose what you invested and made a mistake buy buying in high price tendency is that you can afford to wait for the price go up, and definitely it could go up, its a Crypto's lifecycle
Myself, I don't quite agree with this market truism. First, losing anything, however little, is not a good idea, to begin with, because if you agree to lose from beginning, why trade at all? You start trading with the aim at and hope of earning, right? Further, if you invest only what you can leave to rest, meaning you don't particularly care about the possible loss of your investments, then you won't care much for the profits earned either, because they will be as small. In a nutshell, we have to risk, but definitely not risk all.
