It is obvious, but remember that majority of his assets are liquid so no put in investing all in Ethereum.

But I get your point though, investing is really good if you know how to double your wealth in crypto. But it is a big risk that maybe a few can take that risk. A example that a remember is that guy who sold everything way back in 2017 and invest all his money on bitcoin and travel the world with his family. Not sure what happen to him today, but if he had sold last November when we had an all time high on bitcoin then he has more than doubled his money.
