Please consider withdrawing your bts from external exchanges if you do not intend to sell them.. More than 30% of BTS are in the top two exchanges. This is very dangerous and if something goes wrong with any of these exchanges you can kiss goodbye your bts investment forever.
If you do not sell your bts, why not just held them in your wallet and be the king to your castle?
Many POS/DPOS coins have POS rewards which encourage people to keep their coins in their respective wallets and off the exchanges earning the reward in what is a fairly circular cost.
The 2% dilution to BitAsset yield proposal is a form of POS rewards which shareholders can earn by removing their BTS from exchanges and yield harvesting BitAssets.

(It's hard to be a DEX when as you say you are extremely exposed to CEX risk)
