Dev said they are working on collateral increase & coinswap. Ann about mn rewards during coinswap is very good & effective. I believe that they are working on mn rewards structure with increased collateral with very much carefulness. So that, increased collateral with high rewards cant do coin inflation & keep demand higher.
Why Ultranatum need to increase masternode collateral?
Increased collateral might lead to suddenly rise in MN ROI, but it might not be final solution.
