Bitcoin mining company Riot Platforms, Inc. (Nasdaq: RIOT) sold 1,818 BTC in December 2025, marking its largest single-month sale to date. The company operates mining facilities in Texas and Kentucky, with engineering capabilities in Denver and Houston.

Miners use high-end computers to verify BTC transactions and add blocks to the blockchain, earning rewards in the form of newly mined BTC. However, reduced rewards have made mining less profitable.

Riot’s record Bitcoin sale of $161.6 million in December reflects the slump in the crypto market. The average price per BTC sold was $88,870, down from $96,560 in November. Production also increased significantly, with 460 BTC generated in December compared to 428 BTC in November.

Riot Platforms currently holds 18,005 BTC, down 7% from the previous month. The company’s stock was trading at $14.82 in pre-market hours on Jan. 7, down 1% for the day.
