It were many successful ICO`s in last year , you just only have to learn to choose them righ , and that`s all. Of course investing in ICO have more risks , than trading altcoins , but can give more profit in a long term.
However there were many scam and unsuccessful projects. Investors are becoming more focused and interest in ICO is a litle fading. I think in the future we should wait for gradual changes of all ICO's projects
Problem is that new they've become definitely too many of them to take time to resemble and judge the most rationally we can.
We base all this decision process on hype, buzz in the net.
And because ppl have got that ICOs might be an easy way to make money, a lot of crappy stuff have came out since then.
So picking up the right ones has become more and more difficult.
And nonetheless, even though the project is cool, strong team, things can go bad, just like a crowdfunding happens to do.
