For me, I never invest in any ICO project, even they are not a scam project or not
No longer viable these days, many of them were scam before.
when the ICO is over, when the investors received their coin will dump it in the market, so I only invest the coin are listing in the exchange only.
That is a normal strategy not only by the developers but also the investors who saw the idea of investing in ICO and saw that type of opportunity. It's very risky and newbie ico investors should stop if there are still existing icos.
