I'm not against ICOs and I'm not against good ETH ICOs. But come on they will make any shit idea into an ICO these days wont they. Recently I've seen one really scraping the bottom of the ideas barrel.
I think the ETH ICO era is over.
As long as there are folks who are willing to buy into just about any ICO scheme hoping to increase their investment overnight (and there seem to be plenty), such schemes will probably and unfortunately continue to pop up.
Some of the few real and worthwhile projects will prosper.
