Cryptocurrency is much more riskier than Stock Market because we tend to have the control in our investments and if we make a mistake in our trades and transactions, there is a big chance of losing our investments so we have to be careful and be really knowledgeable to know how to handle the business in cryptocurrency.
Cryptocurrency is purely decentralized and the stock market still has control over them. Crypto is more risky but promises a big profit especially if you do it on daily trading
