40 alqo until block 86400 ( 20 % of block rewards )
Masternode cost = 10000 ALQO
Blocktime is 60 seconds, which means an average of 1440 blocks per day
Daily revenue, supposing 40 coins per block, should be 1440 * 40 / 206 = 279 ALQO
Days for ROI ~ 36 days
my calculus based on ALQO, not the price since alqo price fluctuation.
