I've said it a few times now: Claymore miner DOES NOT give free DCR to miners. Dual mining costs substantially more electricity than just mining ETH. I stopped dual mining specifically because it wasn't worth it. Those who keep just spouting crap they hear need to do some research, because price devaluation isn't coming (at least not solely) because dual-miners are dumping DCR. Besides, as it was already pointed out, Claymore has added other secondary algorithms to mine with ETH, and none of them are seeing rapid price devaluation because of it.
LBRY was mentioned and has been going nothing but down. Might be a coincidence but I didn't even know it could be dual mined and wandered how a gpu-only coin was still getting so much hash at such prices. Now it's not so puzzling any more
Ya, I think that's more due to the massive premine the coin had. Another secondary algo, Sia, is doing pretty well...rock steady pricing anyway...
The only point I wanted to make was that I don't believe dual mining is responsible for the DCR price decline. Too many have the notion that Claymore's miner gives "free" dcr, but that is by no means the case. At least for my electricity prices, dual-mining DCR became unprofitable when it dropped below ~1.60. So I would seriously doubt that dual-miners are just dumping the DCR they make, even if they are still dual-mining dcr.
