i was doin some math lastnite and with 2x gridseed 5 chip orbs i made .0007 and some change more than 1 hashlet on zenpool and they boast about it being most profitable lol they lie like dogs but for the price concidering gridseeds sell for 30 and most of the hashlets are under that its not to shabby
Your comparing apple to zebras.
The orb averages 300khs, you have 5, so 5*300khs = 1.5mhs, so yes, 5 orbs is going to make more than 1 hashlet on zen. Second thing your not accounting for is the cost to run those orbs, the hashlets are charged 8c/day, I bet those orbs run twice that each, if not more.
Even if they ran 8c/piece/day to run, your looking at 40c/day for your 1.5mhs while the hashlet is 1mhs for 8c/day, account for the difference and your looking at an operational cost of 3.5X that of the hashlet.
