This would help big hash miners to catch up to its own hardware limit faster than ever.
1. Run your miner program and check your difficulty value.
Keep in mind that difficulty value must be stabilized.
We recommend you to get difficulty value at least after 10 minutes of mining.
2. Set this difficulty value to worker's password as "d=XXXX"
ex) d=0.0312
Do not write this value to miningpoolhub's worker page, just write it at miner configuration file.
3. Now run your miner program again.
You will see your miner running at the difficulty value you typed.
4. Difficulty value can go up and down again. It's not a bug.
d=XXX just gives us hint at start and it doesn't enforce diff value to be fixed.
Far wrong diff value may corrected automatically, but you'd better write optimized value.
Big hash miners who are using rentals, multi-algo, ASIC would get better result with difficulty hint.
Please can you to be more clear about point "2", I see that claymore setting the diff with number without "dot" example "52216", can you write an example string to put in the config file? Thanks in advance
