I've been using nanopool.org Don't know if that is the best one. Don't know that it matters. But, they had simple configuration instructions on their website, so I just went with that. It took about 3 weeks of tweaking the settings for mining software and GPUs to tune it for the best results I've been able to get. Do other miners get more?

Question about nexus CPU mining. Is mining NXS profitable? Don't know if that is the best one. Don't know that it matters.

Bitfury Bitcoin Gold BTG Mining. But this was more of an experiment for me than anything else, as it certainly isn't going to earn a whole lot, so I'm not too concerned if I don't get the last 1% or 2% of performance out of it. I don't think solo ETH is really viable. If I remember right, block rewards are 5 ETH. I mine 0.1 ETH from pool in a little over 5 days, so on average I'd have to mine 250+ days to find one block if I tried it solo. BTW - I did switch rig to ZEC mining for a few weeks, and it actually earned slightly more. But then two things happened. First, ZEC price fell.

Then, one of my GPUs started throwing constant errors. Calculate BitcoinDark BTCD Mining. So I switched it back to ETH and errors vanished. Must have been something related to the hashing algorithm. I didn't feel like trying to resolve the issue, so just left it mining ETH again. • • • • • • •.
