We are looking to purchase or partner with miners that want to list their GPUs on our platform.
As far as I can recall, GPU mining in bitcoin literally does not exist anymore, you would have to go back to 2009-2010 for that when it was CPU and GPU mining.
However altcoins may still be mining well on GPU, still I dont have any expertise on this matter. I think it would be better if you explain your business proposition elaborately - how you want to partner with miners and how you are planning to bring that to positive sales figures.
