Well I mean you can call pennies a day profitable, but is it really worth the huge upfront costs? I'm genuinely curious how you do the numbers because I have lost a lot of money mining with asics, notably the inno d9, which I'll never roi because of the insane upgrade the upcoming whatsminer d1 will do. So I'm thinking of only mining bitcoin from now on...
Im landing second hand s9s for $250 shipped including psus and Im at .067kwh moving to a new contract of .04kwh. Just because you make pennies a day off of s9s doesnt mean everyone else does.
