Hi, I would like to buy an s5 but I don't know if I will roi since there will be new miners around september. I'm not realy new in the Bitcoin world but currently I only have a usb miner just for experimenting. Thanks in advance!
as always your power cost is ?
and do you have a good psu?
if your power is 10 cents or less and you have the psu maybe you make a little money.
If your power is 15 cents or more you will most likely lose money
If you power is under 5 cents buy one as it is almost a certain profit. If you have a good psu on hand
