If could be possible regarding to PoB to make possibility that people have choice for instance after 80 or 90% of Decayed burnt SLM to withdraw the balance, as with the small amount left, reward will come like never, especially if diif is big. But that would nightmare to implement i believe.
It would be supergreat if there were a possibility to withdraw not yet decayed coins. In context of the virtual mining metaphor it would be as if the miner is selling his equipment at the market price. It would also help us to compete better with Dash's-like Masternodes.
I remember we've spoken about it on Discord and seems like it would require a lot of effort for the possible developer, so maybe we need at least to postpone this implementation for the period when the PoD token will be available.
