The short version

The base A3 trades the Pro’s tuned hashboards for a lower entry cost. It is the unit we move most of on 50-plus container orders, because the capex per terahash is the lowest of any new Bitdeer part and the loop hardware is identical to the rest of the Sealminer family.

  • Lowest capex per Th of the new Bitdeer range
  • Shares fittings with A3 Pro and A4 units
  • Volume pricing from 50 units
