Does anybody else have the same feeling that because this ICO is so huge ($180M invested at the moment) and has no cap, it will be much efficient to wait until it reaches the exchanges and buy in dump due to newbie panic sell at the start for maybe a half price compared in ICO?

without a doubt, yes. you may be able to get this one for a 50% discount if you're patient.
Yep, I just waiting for that... 300mln for far, 3 months later hype will die and massive dump will happen. Noobs will flip tezos for another hotter ETH killer:)
