If the mods are genuine then it will finish in about a second (again, I can't do this myself because no source code => no way to compile on Linux aaaaargh

)I have been a gpu miner dev since 2013. All the optimizations in this mod are real, and I didn't change the algorithm so it's pure teqnique. With more work I can make it faster, but there is no money to be earned so I will return to miner development. Check out my vertcoin miner with 1% fee. Vertcoin is halving in 2021, the price is low..
