Now imagine one LBC for 100$ and feelings of all sheep that currently selling it for a pittance. You know, like all those miners who just mine today's mainstream without any faith in projects. They were selling BTC for 1$, they were selling ETH for 1$, and they will happily sell LBC for the same 1$.

Since Claymore Dual allows to mine ETH and LBC simultaneously, I see no reason not to.

ETH's reported hashrate slightly decreased, but the pool behaves as if there's no difference. So it's like + ~6 LBC per day for free.

Last time I checked, Ethash needed ~2.2 Gb, so you can still mine it. But Claymore wouldn't give me more than ~24-24.4 mh/s (for an overcklocked 1060 6Gb), while EWBF would reach ~330-340 sol/s. The choice is yours.
