Stocks has a smaller percentage of loosing money and earning, but in crypto you will have a bigger percentage of loosing and earning money and what can i say that crypto is very more volatile than stocks.
If you want to earn big profits then you have to take big risks. Stack markets are regulated and controlled by authorities so they can't jump more than a certain percentage on a daily basis but crypto markets are not regulated by anyone so it can go high like crazy and also can down like crazy so you should be careful when you invest in crypto markets.
