If everything is possible in this world, then getting rich with crypto is not that difficult. In fact this could be the most easiest way to get rich in short period of time due to volatility of market which gives big profit in less period of time. I probably suggest you to invest in Remme as this coin can make you rich because this could be the next big thing in security features and once it get identified by more people, it will be skyrocketing.
The only hard thing to do if we talk only about investing and holding is picking a right coin, but if you make a nice shot that won't be hard to just get profit after some period of time. That's why our market become popular that fast.
