You know what bro, you shouldn't say something like ICOs are scam. Because obviously, since ICOs are made by human beings, some of ICOs are also good while others are bad. Just like us humans. So it wouldn't be fair to call every ICO a scam. Just as it wouldn't be fair for women to say all men are cheaters.
And regarding the possibility of your invested coin being a scam would only be clarified by yourself. Do your own research about the coin for goodness sake! Did you even bother to read the white oaper and checked the backgrounds of the developers before you invested? That is a major mistake in investing bro. Better change your ways if you don't wanna end up losing a lot on your investments.
