A solo Bitcoin miner achieved a significant victory by successfully mining block 960,804 on Monday, earning a block reward of 3.157 BTC valued at approximately $199,300. According to mempool data reported by CoinDesk, this success follows another solo miner who mined block 957,382 three weeks earlier, also earning 3.1382 BTC worth roughly $200,000 at the time. The latest mining success involved a solo miner on CKPool who rented approximately 100 PH/s of computing power for roughly $25,000 per week and successfully mined the Bitcoin block worth the estimated $200,000. These back-to-back wins highlight the continued success of individual operators despite broader market challenges, with solo miners already claiming 13 blocks this year.
The mining success comes as the broader Bitcoin ecosystem faces significant stress from the ongoing Coldcard hardware wallet exploit. As reported by CoinDesk, the incident has led to potential losses of $114 million as a fourth wave of sweeps against bitcoin addresses generated by the Coldcard wallet began Monday and continued for hours. Onchain data shows the BTC exchange reserve has risen to 2.718 million BTC from 2.706 million BTC on July 30, the day the incident began. However, analytics firm Glassnode argues that holders are migrating coins to new wallets rather than sending to exchanges. The exploit has created additional market volatility, with Bitcoin dropping below $63,000 after a 3% fall following failed recovery attempts.
The mining success contrasts sharply with broader market sentiment affected by the Coldcard incident and recent market volatility. According to CoinDesk, the number of BTC sending addresses spiked on Friday to levels not seen since early 2024, with small BTC holders expressing frustration over lost Bitcoin savings. The wider Bitcoin mining sector faces additional pressure from tight margins, prompting several large mining companies to pivot toward artificial intelligence data centers and related infrastructure in search of sustainability. Rising Treasury yields, including mortgage rates, pose potential headwinds to risk assets including cryptocurrencies, while Bitcoin and major cryptocurrencies have declined as AI and semiconductor stocks cooled, highlighting their linked risk exposure.
