I still didn't get why ICONOMI changed their original plan of distributing dividend to buyback. If Taas can pay dividend, why can't ICONOMI?
ICONOMI has become concerned about getting in trouble with the American SEC as an unregulated security. Many think poloniex will not list ICN because of this. So the devs changed from dividends to buyback-and-burn to distribute profits. This will make ICN increasingly rare.
TaaS has yet to distribute a dividend. They may change plans too.
ICN would still be classed as a security. Buybacks won't change that. I think there's more going on with regards to the whole buybacks/exchanges thing.
As for TaaS, I guess we'll have to wait and see.
