doesnt look like their going to fix a3's on mph. i got a email saying the a3 doesn't support mph and i need to contact bitmain to have them support it. so i guess i won't be using mph anymore.
if they are not going to support the A3 they might as well just shut down that pool now. The difficulty has more than tripled in less than 2 days. A GTX 1060 6gb is 20x slower than one A3. Mining with GPUs on Blake2b is a waste of time and money unless you are using ASIC. and the makers of the dragonmint16T announced a Blake2b ASIC miner they are releasing that does 3.5TH at only 1000W which puts the A3 to shame already so these will follow the path of the D3 and become a nice space heater in about 4-5 months.
