In 2017, the year when ICO's are pretty good, there is allot of investors in the market, now in 2018, I see few, in this case, one reason is possibly true that ICO's cannot reach their caps because of lacking investment through investors.
should it be the evaluation also, why many investors ico thus reduced where a growing number of ico. perhaps also because this year many ico scam which simply eliminate the investors money. so it made investors more careful in choosing the ico.
