The ICO is no longer as organized as it is in 2017, but there is a strong improvement in the quality of each project.
They are just having difficulty with the current crisis market, once everything starts to recover, they will move forward.
So I think there is no problem with the ICO in the future, maybe the number of new ICO will drop a lot, but the quality is not worried.
It is a good opportunity to invest from the end of this year to next year.
