I don't think it's possible to get rich easily in the crypto market, otherwise everyone would be. But there are some possible ways (easy but risky).

We can choose to invest only in ICO, if the project is a success the benefits can be very important (given that we invested very early). But there is a great risk that the project will not succeed and everything will be lost.

We can also play with leverage on several sites, there again the gains as the losses can be important.

I think it's still best to find a mix between risks and rewards
