Replacing these under-performing miners with the new M60S model will have a positive effect on both our operating uptime and energy efficiency, as these are the most efficient miners ever produced by MicroBT. The investment made in this purchase order strengthens our commitment to be a leading low-cost miner and further enhances our industry leading fleet into the future."
