Most ICO projects in 2018 become scam, basically they do not have real projects and seek funding through the ICO. So be careful before investing in ICO.
If we consider the ICO projects in the early 2016, we can see that almost each of the project from that time made immense profits and is yet a profitable project but projects after the mid 2017, were been started just to collect the funds and get away from the markets.
There were a lot of ICO's which ended up being scam so ICO investments is always being treated much risker now. Investing in something we already know is good to avoid such losses.
