The worst thing you could do right now is to become cynical just as crypto enters its scale up phase. Yes, plenty of dumb ideas have been tried that didn't work. Yes, there were scams and people got rich that didn't deserve it. But just because something has been tried before doesn't mean it's doomed for failure perpetually. I think many of the ICO era ideas were good, they were just too early because the infra wasn't ready and regulation was too murky. Do not make the mistake of throwing out the baby with the bath water. Nothing is more powerful than an idea whose time has come. That is crypto, today.
