Am not sure why did they mean ICOs since its usually happens and Even the bitcoin doesn't implement any ICO to increase the funds or value. Those kind of predictions are meaningless for us.
There many practical examples that ICO will not raise its value but the funds on their hands.
It may strongly based on the increased usage of bitcoin where investors attention.
Probably many alts investors are turns their money to bitcoin. Just my thought.
Forbes or anything will not think like forum people and we are real time participants in crypto for possible ideas
