I would say join an ICO could be the faster way of nice revenue at present and those are in amazing health presently.
Undoubtedly you can get a lot more profit from investing in ico projects. But you need to be able to choose such projects. There are a lot of fakes and scams on the market. If you invest in their project, you will lose all your money.
I agree with you. Basically, investment in ICO projects is very profitable, but determining a good project is the key. At present it is difficult to determine a project that is good or not because there are too many projects and some of them have bad goals.
