Why not? Cryptocurrency is a really good investment for sure. So anyone who is investing in them is going to benefit from it. The cryptocurrencies you have mentioned are really good, but I am not fully sure about that Dogecoin that is there, although it was bullish, but it is clear that was triggered by price manipulation.

So, you might have to avoid coins that can easily be manipulated and invest in the good ones that can be more stable. Tether is a stable coin, but you can still useit, some people use it as a savings and also to save their money when the market is bearish. Tether is a big coin and is very stable, another one is DAI. I like Cardano and I am investing in it also, and Bitcoin is always the first thing you get to know about and a truly decentralized cryptocurrency.
