Decoin was advertised as "The FIRST blockchain Profit Sharing Exchange platform" in 2018 (it's even included in the name of this thread). Now still after 3 years, there has still been no profit sharing to token holders. Quite misleading.
Yes that's the only goal they have yet to achieve. Although they have achieved most of their targets like staking etc.
I think they have change the plan because if they share profit with token holders, their coin will be considered as security token and they have to face legal hurdles.
