most of the dash is currently locked in masternodes
Just to clarify. No Dash is "locked in masternodes". This is a fudster myth

(A popular one, but still a myth).
It's locked because it generates money without any work and no one would unlock/spend a resource that generates money without the smallest effort. Even more if the price of this resource grows.
Do you really think that someone will ever invest in a financial system that benefits only couple of thousands people on the planet who will be like kings for eternity like in the middleages. Where is the fairness here. This is even worse than the middleages. And only because these several people once had the luck to instamine on a broken code. Oh my little funny dashers, you are delusional. Enjoy the temporary pump of this scam though.
