I have gotten as much as 60 bonus MH/s with Mintsy.co off of 4 contracts for 10Mh/s each. Pretty amazing. Kinda sucks when it goes the opposite way like right now and only pulling about 6Mh/s per contract. There are a couple questions I have been meaning to e-mail but might as well fire em off here.
When I purchased my most recent contract, I was attempting to buy two 10Mh/s contracts for 6 months, but I believe they have been combined into one worker. I believe this happened since my 3rd worker has an average of double the hashing rate as the first two workers/contracts I set up. Is this something I should worry about? I have 4 workers listed on my account but the 4th is 'inactive' and my OCD doesn't like that
Also, should each contract be linked to an individual worker set up on the pool's website? I believe I read something along those lines on the website.
As for setting the difficulty on a mining pool, I know it is dependent on your current hash rate, but with mine having a relatively wide range of fluctuation, I don't know what to set it to in order to get the best bang for my buck. I have been setting it to 64 as most pools mention over time that is the best value for all miners.
Lastly, does a scrypt miner handle scrypt-n and jane?
