My POV is that ICOs are playing the lottery. It's a lucky chance that the bucks you put into an ICO will turn into large quick gains. The only reason an ICO will shoot up hundreds% is because of manipulation. Having said that, it's pretty easy to put $20 into a coin worth $0.000004 right now... it seems easy for that coin to shoot up to 2 or 3 cents.
