Not all the coins in crypto are volatile as you think because there are lots of stable coins to be used instead such as USDT, USDC, BUSD, and more. You don't actually need to use volatility coins like Bitcoin if you can't take the risk. This volatility makes this market very attractive for investors and being decentralized so that no one can manipulate the whole market makes it challenging and interesting. Sure it was a lot riskier compared to other markets but along with it, the profit was really rewarding. Investing in Crypto is just like having a 50:50 ratio, 50 percent chance you could lose half of your wealth especially if you really have no idea what you're doing but you also have a 50 percent chance to grow it a couple more times.
