Triode, you talk about avoiding suprnova... Why? Is it not good?
I'm indifferent to suprnova, but others in this thread have been looking for options outside of it. I find zpool to be very easy to get into since it doesn't require registering an account or anything. I also like the yiimp style interfaces, personally, so that's another plus for zpool for me.
Through some indirectly-related searching, I found another POLY pool... this one more mid-sized: https://pool.coin-miners.info/site/mining . From what I've seen in the past couple days, this pool seems to have a consistent hash in the 1.6 - 1.8 GH/s range putting it at about 4-6% of POLY'S network hash. Based on that site's "pool" page, it anticipates mining a block about every 50 minutes or so. The pool's fee is 1%, which isn't very sizable. I've mined a few fistfuls of POLY there since discovering it.
Anyway... so long as the pool one is mining at actually finds blocks regularly (if a person mines consistently and fees aren't substantially different between pools) one should expect to earn about the same on average no matter the pool. So, this one should be a contender in helping distribute the hash among other pools (in addition to Zpool.ca and Cryptohub.online) if people are interested in making the chain more robust.
Also, if the pool operators aren't making an effort to get their pool listed in the OP, hopefully the thread-owner can add the links to these pools in the original post(?).
