Hi . I would like to know if you have returns assemble a machine to mine with gpu ?
or mine with gpu is losing money.
I have in mind to mount a machine with 6 gpu
Since this is a Bitcoin centric forum, and not altcoin related, I'll respond as such. It is no longer economical or useful to try and mine Bitcoins with anything but an ASIC. The electricity cost alone will exceed the value of the Bitcoins that you mine. If you wish to mine at a loss, then GPu's will work fine. Six GPU's will only mean that you lose more money than using just one.
You should probably sell most if not all of your GPU's, and buy a used ASIC miner to see if you like it.
