Never, I have been liquidated, seen my shitcoins go to 0, and lost an account (because of losing a 2fa device)
But I still believe crypto is the way forward, the whole evolution of money from coins to paper money to digital money to cryptocurrency, is a natural and inevitable move.
I also lost a lot, but I still believe that the cryptocurrency is our future. Mankind will be using blockchain technologies for centuries. The crypto will be more popular than fiat. Thus, invest in it.
