I am staking (24/7) nearly 17000 and receiving average 16 rewards daily (16*4.0489=64.78) No VPS payment
== Compare ==
MN daily reward (7*5.85=40.95) + 7000 staking ( 7000/16000=0.4375 , 0.4375*64.78=28.43) ==> ( total reward amount = 69.29 ) (cut VPS payment from your profit)
Correct me if I am wrong
That was fine formula. But do you count for any orphan block cases? I just have bought the same amount 7000 coin from exchange to stake, but my receiveing average daily is only 6~7 times in which 1~2 orphan blocks.
