I think ICO started to increase day after day and people started to trust it,The future will goes to ICO, maybe because the low price or the new features which it provides.
now ICO is not much in demand, now investors are more interested in IEO, specially launch by popular exchanges. Even the future is changing so fast and will wait for another innovation in the crypto world
Chances are there will be much less of ico going on in nearest future, simply because of what you've just said - investors are not interested in risly fraud schemes.
However, scammers are not interested in starting and ICO knowing for a fact they won't get any money.
So I hope we'll come to the point when ico will be a normal thing to do again
