Here at Great American Mining we were one of the first groups to break free from the Bitmain strangle hold and go with the Whatsminer M20S.
We’ve been running these units for close to a year now in the harsh environment of the North Dakota Oil & Gas Fields.
We’ve replaced a couple of PSU’s out of a batch of 160 and we’ve had ZERO miner failures over the past year. Its a tank-- it boots up in -20F weather and just screams louder when its 93F outside.
We look at the M20s as the S9 of this new Bitcoin halving epoch.
