Imo via probability LHR will be fully hacked at some point long term. May or may not matter anyway since new algos will come and go on which these cards can mine successfully. I keep my eyes open and enter shuffles for ANY modern card I can reasonably afford, LHR or not. 3060 LHR I have mines rvn very well and is efficient.
It's what I think too, it's only a matter of time before we see a new hashrate unlock for 3070ti and other LHR cards, ravencoin on the other hand only makes sense if the profit is better cos that algorithm draws more power than ETH mining, today Sero coin is the most profitable on 3070ti but I stick with ETH because other coins drops faster in profits and I can't keep changing Alfi all the time, by the way ETH saves more power
I'll have to try again with nbminer with the LHR. I was somewhat early with miniz on the unlock and with a lot of optimization work on RVN it's nearly neck and neck RVN vs Eth. I'm getting nearly 22mh at 113 watts with RVN. I'm more or less spec mining on RVN for now, seeing how many I can put away until the halving. I'm flexible though.
