If warren buffet believes in crypto just like how Elon use crypto to multiply his assets , Warren should be the richest man on earth until today.
We don't know about this, Buffet isn't the same as Elon. So, there is no guarantee Buffet can be successful in crypto. Elon has done a brave decision to invest in crypto, buying Bitcoin for Tesla and he also used a good strategy. Elon even used his popularity to influence crypto market, it was a crazy thing. If Buffet invested in Bitcoin, I don't think he will be the same way as Elon did.
