To be honest i don't blame people for asking 100 millions if they just get more by asking it. But the investors were also greedy to think that it would be easy to rise value after so huge market caps.
That's really what happened last year, people threw money blindly at ICOs because at the start of the boom, on tokens listing you wer almost guaranteed with a 5X to 10X return. For quite some time it's not the case anymore
