I disabled zpool.ca from all my 1273 RIGs to avoid future loses and I advise you all disable zpool until they will fix the issues and until they will monitor the pool and avoid high loses we all have.
They will not be used anymore and will go to 1k miners soon (like it happened with HashRefinery, now they are out of the market, nobody uses them anymore) , if they continue to cause us so many loses.
Zpool also charges
2% pool fee + 5% exchange fee = 7% total fee from zpool, and that is a lot more compared to many pools that have 0.5% fee. I advise you to search and use lower fee pools for higher profit.
