Given the forums we are in, it's more likely that people are realizing the price of IOTA is rising and are now angry and jelly they missed the ICO than they are thinking or caring whether it is a scam.
Yes I think that may be the case. I've seen some complaints by people who say they weren't aware of the ICO and now can't buy in at a reasonable price. They also complain about transparency.
I was aware of Iota early on (because someone PM'ed me asking me about my opinion of it) so I could have bought in, but I didn't because I analyzed the technology and was confident it is flawed. Also I was immediately turned off by David (iotatoken)'s unbalanced hyping of it. I don't invest for short-term gains. I invest for the big enchilada over the long-term.
