Billy Markus, one of the Dogecoin creators, is well known for his skepticism of cryptocurrency investment.

He made a statement about it once again this time, comparing it to  “investing in mental illness.” Additionally, he said, cryptocurrency  investment is growing.

Just like Dogecoin was created as a spoof on Bitcoin based on BTC code,  Markus is well-known on the crypto Twitter as “Shibetoshi Nakamoto,” a  parody name for the enigmatic Bitcoin developer Satoshi Nakamoto.

Markus said when questioned about NFTs that because it is a derivative  of cryptocurrency, investing in it causes individuals to become “even  more mentally ill.”
