Stocks are for long-term investment. You can still receive dividends each time the company distributes profits.
Crypto is more suitable for speculation and trading.
I find this is a good time to trade crypto instead of stocks because I know the crypto market is in a strong bull run.
If you feel unsafe investing in one side choose both.
And also, some people are not yet comfortable with crypto because it is relatively new market as compared to stocks. If you don't know what you are doing in crypto, you can easily lose your funds in an instant. So this question is quite dependent on the person himself. Some people here who are already long enough to know crypto prefer crypto over stocks, however, for just newcomers, some of them will prefer stocks over crypto, because they know the stocks market better than crypto.
