I have not get good luck in investing into icos and the few one that I have invested is not doing very well in the market. Icos investments is very risky and many investors have lose significant amounts of money. I don't think we can really succeed the ways people and investors are losing money through icos scam projects.
maybe what you experience is the same as most investors currently taking part in the ICO because at the moment it is very difficult to find ICO which is really profitable in following the ICO
