I am sure that investing in ico is still very profitable. It all depends on the choice of ico. There must be knowledge to determine a good ico, to extract earnings from a promising ico.
What ICOs you have invested so far? Have you tried Welltrado?
I never invested in that project, but don't just rely in only one project because there's a lot of potential coin to be invested. I believe there are more legit ICO so must read there platform first before investing them to have security and at the end will able to earn good profits.
