if it's the case that the return on staking at Binance is indeed due to the balance being actively traded (which I'm not saying it does, but if it were) then at least that ROI has some real economic basis. That is to say the return comes from OUTSIDE of the Dash ecosystem and nourishes it rather than coming from the blockchain itself, thereby eating up the capital value of the chain and spitting it out into masternode pockets without them having to replace that value (in the way that, say miners do).

Just something to think about.
