I watched a video by some Russian guy named Crypto Leo. He had a Zotac 3060 and was given credit in a article by videocardz.com as confirming that on ETH it did indeed cut the hash rate in half.
What the article didn't go on to say was that in a follow up video he tested the 5 top money algo's out right now and the card actually did close to or better than a 3060 TI in 3 of them. Octopus, Cortex and Cuckatoo31. All of which give this card a great ROI at under $400.
Exactly, it only halves Ethhash algo. There are a few Algos that are close to Eth profitability wise that you can mine and ROI pretty quickly and then switch later if there is ever a fix found for Ethhash.
