A solo miner has claimed Bitcoin block 960,804, securing a reward of 3.157 BTC valued at approximately $199,300. This follows a similar achievement by another solo miner three weeks earlier, highlighting the continued role of individual miners in Bitcoin’s block production.
Recent activity has raised concerns over a multimillion-dollar exploit linked to Coldcard hardware wallets. Reports indicate ongoing address sweeps, with increased Bitcoin movement to exchanges observed by analytics firms. The situation has prompted scrutiny over wallet security and potential vulnerabilities in the ecosystem.
Bitcoin exchange reserves have risen to 2.718 million BTC, up from 2.706 million BTC on July 30. This increase coincides with rising U.S. Treasury yields, which some analysts suggest could pressure risk assets. Meanwhile, the Senate left the Clarity Act off its agenda during the summer recess.
Glassnode noted that data suggests Bitcoin holders may be migrating coins to new wallets rather than sending them directly to exchanges. This interpretation contrasts with reports of address sweeps, which remain unconfirmed. The potential scale of Coldcard-related losses is estimated at up to $114 million, though this figure is subject to ongoing investigation.
The frequency of solo miner successes—13 blocks mined this year—underscores the decentralized nature of Bitcoin’s network. However, the exploit concerns and shifting on-chain activity highlight persistent challenges for users and institutions navigating the cryptocurrency landscape.
