And i also thik who will invest now in crypto he also will profitable there has no doubt. So i think investing on crypto is Safe now.
I quite agree with you, crypto currency is actually the biggest invention of mankind in the area of finance, bitcoin started like it was not going to succeed, even the creator of bitcoin was not sure about bitcoin succeeding, the prove of this can be seen in a several of his comments to the bitcoin community, before he finally decided to completely turn himself off from the community.
Ever since thie, bitcoin have continued to perform really well in the market, and to this, I would also say that, investing huge amount in crypto is a very good idea, as long as it's an amount of money the person can willingly let go if lost for what ever reason.
