the one above is an okay price I dont know seller.
I strongly agree with this setup.You know that mining DOGE which is a low price coin is better in these times,mining LTC+DOGE is also great so I think this is the best you can do.No matter we have already entered negative territory for many GPU-s of 4 GB which cannot be profitable anymore unless you have free electricity and mining those coins can be a good option for the longer term especially on that DOGE thing as you can mine a small amount of them daily and during the long term it can add up to be a nice amount.
