Bitmain Antminer KS3

An earlier Kaspa generation carrying almost the same power draw as the KS5 Pro for around 40% of the hashrate. Hard to justify at current difficulty.

Recent mining coverage

Bitdeer Mined 1,310 Bitcoin in August and Ended the Month With 61
Business

The miner's self-mining hashrate rose to 79.9 EH/s and production was up about 249 percent from a year earlier, but its bitcoin balance ended the month at 61 coins, against 257 a month earlier and 1,934 a year ago. The company's own footnote says the figure counts coins pledged as collateral, which rules out one explanation for the drop.
