- I currently think an ideal cryptocurrency coin emission curve includes a tail emission.
You don't prolly don't need it with PoS combined. Tail emission doesn't provide enough security any way, so you've go to get a handle on the fee market issues. Thus the reason to want PoS control. But democracy is always a winner-take-all power vacuum.
-Proof of stake mining has a genuine penalty (coins locked up)
That is actually a good thing for making the price go up because the float is smaller. Dash's masternode scheme with compounding concentrating stake to Evan Inc is a perverse example.
True and true.
By having one's coins locked, it also requires people that wish to vote on Decred's future to have "skin in the game". It's not a perfect system, but it does incentive people to vote in Decred's best interest.
