I'm sure Bancor couldn't care less about their token price collapsing. They've already got all of the "investors'" money. In fact, they could just walk away right now instead of carrying on developing the system. The brave new world of ICOs offers no protection against companies failing to follow through on their ICO roadmap. Maybe Bancor could use the token collapse as an excuse to quit now?
The brave new world of crowdfunding is not that new, but the allergic reactions to it seem odd.
