You do realize they are waiting til there is a stable wallet for mining.. I've been on ipominer.com for quite some time, if they say there is still issues.. you can bet there is still issues , I believe its with the daemon. someone should maybe pop in #ipominer and have a chat with the pool Op there. The potential hashrate is huge if you get them on board.
I starting mining with IPOMiner as I've used them before but then they disabled everything and locked the funds.. while there was some issues, it was for a very short time...and then no updates from them, and no release of the SYS that was already mined... since they disabled their port and literally a few minutes after the announced fork I've been mining on Syscoin.me (almost a week now) with not a single issue and received every coin from them without issue..so mining is working.. also great support from them, very active with the community via IRC.. while it would be great for SYS if IPOMiner could update and it would bring a large amount of hashpower if they put it in the rotation and direct port, at this point I am sticking with Syscoin.me for my mining.
Aye, Syscoin.me is indeed good, and are doing great support. As for IPOMiner, no idea. We will reach out to them again shortly
