Is there a way to get work difficulty to be adjustable? With work difficulty at 1012, it's hard for those with very low-end mining rigs...
I think the difficulty is static at 512 not 1012. And although you won't be getting shares rapidly, they are still worth more than a share of say diff 16. You'd have to some math to find if a vardiff server is more profitable or not.
No difficulty is set at 1024.
