Anyone know anything about middlecoin payout address 1M3jtksp1upR33SX1VzeCfH5x9fc6zKykR? 500 mhs seems hard to believe. I wonder if it's a company and hundreds of gpus are running in the same building or if it's many different places all hashing to the same address?
It was confirmed by h2o that it's a legit user in China.
