Today the ROI of MID masternode is 99% , i received 1 stake every 18 hours, in this mode i lose my money, because if i  received under of 100% , the coin i have burn is 500.000 and i received less.
when i have start masternode you guardanted a roi of 112% ( if i remember good) , after you open unlimited node and now the old masternode  receved less coin. Why? you don't have think  this?
