Yes, i do believe in cryptocurrency. There are many people who are earning pretty good. If we talk about we all will be rich one day?? That's not sure. Because cryptos is all about experiences. If your basics are clear , you know how cryptos works, what is the right time to invest, if you have capability to understand present and past trends only then you will be able to survive in cryptos. So you just need to put maximum efforts if you want massive returns.
