I bought a Baikal A2000. It does the polling to find the greatest pool payout then mines it.
What distresses me is that the X14 Berncoin always shows the greatest payout so the A2000 switches to and drops the X11 mining.
The device stays on X14 even after all blocks have matured. My device web page shows top hash rate yet no monetary input to my Zpool account.
I had to go to the device web page to hard switch to X11. Things were stable for a while yet the payout is not as high as X14.
Then the inevitable happened. The device switched back to X14 and took off mining that again. I will watch the maturing blockchains to see if when they are all confirmed will the A2000 stays stuck on X14.
The sad thing is that the payout is great but where the 2% fee is not.
I feel the bern.
