If you invest your money into right projects probably yes. But right now I think answer is no. This is not regular market, that is why it has crazy ups and downs and people are making money on that. But if you find f/e right ICO you can make extra profit, x2 is typical situation. So find a trustworthy ICO project. However, it is quite a complicated topic, cause among all of the existing projects there are a lot of ones that should not be trusted at all. I am working in this field for a while now, and, sometimes I had a really bad experience with some platforms. However, I have found a really safe application. It is called Kelvin-blockchain.
