I don't think that is FUD mate. There is a lot of ICOs currently and one eat maret share of another that is all.
Sure that ICN is security (profit sharing) but after all if they are buying back tokens WHO CARES ?
Even if ICONOMI will be last buyer on Etherdelta who cares - if they buyback those tokens for real ?

If ICONOMI people will be honest ICN token cannot be stoper even if it is security.
Maybe it will be less pumped but it will gain value over time for sure - if devs will keep buying back.
