Thats a curse of the ICOs - but also a benefit. As an investor you get to assign value to something immediately and have the freedom to terminate your investment (something very difficult with traditional angel/VC rounds) and sell the tokens. Its also a fascinating marketing strategy - some of your crypto "investors" are early adopters, promoters and users of your tech - even more so because they're vested in it.
I'm not defending the ICOs (especially the over the top ones) - but lately there are so many articles that don't really try to understand the concept. And so many people automatically equating temporary loss of value with scams. Internet and cryptos are moving at the speed of thought - but the rules are still the same - startups need time.
In all fairness - Bancor is still a very young project. Also a fairly promising one - many projects already using it: https://www.reddit.com/r/Bancor/comments/75b7us/list_of_all_...
