There was a recent comment on Reddit that during the first dot-com bubble there were a lot of people who just used start-up money to have fun. That didn’t really happen a lot this time and people now in SF are super famous for their irrational belief in their company and working 130 hour weeks ala Melissa Mayer.
Anyway I think ICOs are like some start-ups in the first bubble, using the money to party because no one is looking closely. After all, if you have a great company or a shit company, you still raise the same amount of money. Why work hard when you know the upcoming bubble correction will wipe out your gains?
