Bitcoin sold as a % of Production
The total amount of bitcoin mined during the month of October for all the Bitcoin miners in the chart below, was 5,643 Bitcoin. The total amount sold during the month was 5,858, representing 103.8% of the amount produced. Hive Digital were excluded from the calculation as they did not release data of Bitcoin sold.
As the 2024 Bitcoin halving approaches and the price of Bitcoin Is seeing a resurgence year to date, Bitcoin miners have been taking advantage, to purchase more efficient miners with the likes of Cipher, CleanSpark, Iris Energy, and Riot Platforms taking advantage and placing large orders for the latest, most efficient miners available from Bitmain and Micro BT.
Total Bitcoin mined
The table below illustrates the Bitcoin earnings exclusively from self-mining and does not encompass the additional benefits Texas-based miners have recently been capitalizing on from their energy strategies.
In October, Marathon Digital maintained its standing as the world's largest publicly-traded Bitcoin miner by successfully mining 1,202 Bitcoins. This achievement may be surpassed in November, as the company is poised to energize a substantial amount of hash rate in Garden City, Texas.
CleanSpark achieved an impressive 633 Bitcoins during the month, crossing the significant 10 EH/s threshold. The company has substantial miner orders in place, with plans to double its hash rate capacity by early 2024.
Riot Platforms is currently in the process of energizing more miners in Buildings F and G, utilizing immersion cooling technology. This effort is set to elevate their hash rate to 12.5 EH/s by the year's end, with an additional 7.6 EH/s scheduled for energization at the Corsicana site in Texas during the first half of 2024.
Bitcoin mined per EH/s per month
The table underscores the remarkable production consistency among the top miners in terms of production by EH/s over the initial ten months of 2023. Bitfarms has exhibited an unmatched level of consistency, securing the top position, while Hive Digital, Iris Energy, and SATO Technology occupy the next three places. The actual gap between the top 6 moners is only 3.9%.
Notably, the three miners at the lower end of the table have shown a progressive increase in their performance over recent months. This positive trend positions them well to capitalize on the upswing in Bitcoin prices.
