Far as efficiency, it seems like LBRY is now even with Ether. And I can up the monthly earnings by 20 dollars gross by cranking my power limit all the way up for 285 MH/s. Good while electric is free for me at the current moment but I may wake up to find those earning to decrease further.
People in the LBRY ANN thread see this pump and dump as a buying opportunity. Suggesting that when the premine is done and the LBRY gets incorporated with big studios, the price will surge.
I may just hold what I have now and mine a bit more.
