Well, I just wanna say that some ICOs just make investing in ICOs very risky and uninviting, but I must assure every one here that some ICOs still have good credibility, like for example, I invested In student coin ICO when the price was about 0.008 usd, though they were listed on exchanges while thier ICO was ongoing, now the token is trading on exchanges for about 0.013 usd which implies that if am to sell now, I will be making some good profit, but I believe the token still have a long way to go.
So this is just to say that not every ICO is bad, and this goes a long way to confirm that in a community filled with good people, there must be one or two or even more bad people, bad eggs.
Be careful of what you are aiming here because sometimes, it is better to sell while you are still in profit. Don't wait too long, because that opportunity may go away without a warning. I have learned my lesson well in these ICO projects. Very few can withstand the market and grow their value. Most of the time, after short increase, they go down, and they never get back. So look for reasons why they can keep their value and grow overtime. If not, better sell it while you are in good position.
