I guess it can't be helped, many ICO were turned into scam projects and investors lost their money.
Once we see something wrong in some ICO, we will say that ICO is scam which actually doesn't like that.
My suggestion is, we must take our time to do some research and then we can say it scam or legit.
In this market, the investment in ICO projects is the most risky and most are projects that are not well known. I think at this point investing in ICO is unnecessary and we should only choose the available coins to make a high profit because in the past year many good projects are being forgotten and that is Good opportunity for you to start investing again. In my opinion, ICO and IEO are all forms of calling for capital but the IEO will be much better because IEO projects are often protected by exchanges so it will help investors a lot.
