A mistake I made was putting all my money into a single crypto, so today I have diversified my money into 5 different cryptos. Because I thought my amount was small and it wasn't worth being spread across multiple cryptos.
Summary: I lost a few cents. So it's not a big deal.
Warnings: start with small amounts, otherwise with beginner mistakes you risk losing a lot. And you will invest larger amounts once you have experience. #erreurs_debutant
