Everything in crypto is a risky investment so be careful even if you put one buck as an investment. However, if you don't take the risk, you can't gain profits.
Cryptocurrency market is highly volatile that's why we call this investment as a risky investment. I hope you can understand now.
I have heard people telling that you can become rich in really short time with cryptocurrencies, and I think it is true but with the condition of investing high amounts of money as well, after all, the money isn't actually growing in the trees.
