Stock trading and Crypto trading is an entirely different things. Each has its risk level, hence each return/profit is also different. If mainstream people say that stock is a high-risk asset, then cryptocurrency is a super ultra very high asset. The key to answering "which is better" depends on your skills and knowledge. A skilled trader can get rich pretty quickly in crypto with leverages and stuff, but the average Joe can get rekt overnight... look at $LUNA, $FTT, $CRO, etc.
