Using Claymore's?

yes latest Claymore with dual mining of Siacoin , enough to fill the cost of electricity..

are you not worried about the drop in Hashrate the next view weeks, i heard especially the Rx series will get a harder drop.

Not Really i will get my return in 2 months or so by mining Ethereum and after that if it's not profitable i will move on.
but do not believe what other People say on the Internet, they want you to be afraid and not get involved in mining so that they can make money for a longer period of time.

You don't have to convince me, i am mining Ethereum, Decred, Bitsend and Burst at the same time. But the drop is real, thats why i think its risky to bet on one horse, how much money have you payed for your 6 GPU Rig?
