In light of recent changes in the Bitcoin mining industry and the effects of the halving event, older ASIC mining rigs like the Bitmain Antminer S19j Pro and Microbt M30S+ are now being sold at much lower prices. Luxor Technologies has reported that these models have seen price drops of 28% and 35%, respectively, since September 2023, as stated by Bitcoin.com.

The decline in prices is indicative of broader transformations within the mining sector, largely driven by reduced profitability of older rigs due to a lower hashprice of approximately $0.056 per terahash per second (TH/s) per day. This metric measures the daily potential earnings per terahash of computing power on the Bitcoin network.

This trend is not unique to Bitcoin as other PoW crypto assets utilizing different algorithms are currently proving to be more profitable than those utilizing the SHA256 algorithm like Bitcoin. It suggests a trend within the mining community towards more profitable or less competitive mining opportunities.

Newer models from manufacturers such as Bitmain and Microbt remain dominant in terms of profitability, with devices like the S21 series and M63S, M66S, and M60S models showing high profitability. This underscores the importance of technological advancements in maintaining competitiveness within the mining industry.

These market shifts indicate an ongoing evolution in Bitcoin mining, highlighting the significance of newer, more efficient technology for sustaining profitability. As the industry adapts to these economic changes, older equipment is becoming less relevant, resulting in lower prices for those willing to invest in less efficient technology that may come with higher operational costs.
