I see your sentiment and I tend to buy into your idea not to involve myself in icos, but sometimes one can spot an ico that is exceptional and have the potential that could be a big deal, and be part of one of the big players like Btc, but it's difficult to know from the ico stage.
Yet not to miss out one has to do his due diligence to research if a new coin has a potential market base and is user friendly and if it will go far beyond its ico stage. I hope I made sense
