If to get big and fast gain then I choose cryptocurrency. Because with cryptocurrency we can get bigger clutch than stock market. However, cryptocurrency is at risk and it needs to be considered before you invest. So choose what you think is good
In my opinion, I'll rather choose Cryptocurrencies than Stock Markets, because in Crypto you can earn a lot of profit, and also you can see the movement of the price in the market, and also you're the one who's handling your own money, which means you're responsible for the loss that you'll make, unlike in Stock Markets, you can't see the movement of the price and the profit is terribly slow, and still there's a risk. There's also a risk in Crypto, but the gains are huge and it's really legit.
