An independent Bitcoin miner achieved a significant milestone while the cryptocurrency market grapples with the aftermath of a multimillion-dollar exploit involving Coldcard hardware wallets.

Data from mempool indicates that the miner successfully mined block 960,804 on Monday morning, earning a block reward of 3.157 BTC, which is approximately valued at $199,300. The miner's specific hardware setup has not been disclosed.

This success follows just three weeks after another solo miner, operating a single Bitaxe device, mined block 957,382 and received 3.1382 BTC, valued at about $200,000 at that time.

These consecutive achievements underscore a notable trend within the Bitcoin mining community. So far this year, solo miners have secured 13 blocks. While individual miners are managing to succeed with relatively basic equipment, the overall Bitcoin mining industry faces challenges due to narrowing profit margins, prompting many larger mining operations to transition towards artificial intelligence data centers and related infrastructure for sustainability.

In the meantime, smaller Bitcoin holders are expressing dissatisfaction regarding the Coldcard incident, which has resulted in significant losses of their long-held Bitcoin assets. Recent on-chain data revealed that many Bitcoin holders have begun moving substantial amounts of Bitcoin back to exchanges following the exploit.

On Friday, the number of Bitcoin sending addresses surged to levels not observed since early 2024, as reported by CryptoQuant. The Bitcoin exchange reserves increased from 2.706 million BTC on July 30 to 2.718 million BTC after the incident began.

Other analytics firms suggest that holders might be transferring their coins to different wallets instead of exchanges. According to Glassnode, "The data indicates holders are migrating their coins to new wallets rather than sending to exchanges."

Additionally, climbing Treasury yields, including those for mortgages, could create challenges for risk assets like cryptocurrencies.

On the regulatory side, the news is not particularly encouraging. Reports indicate that the Senate excluded the Clarity Act from its agenda for Monday. With the Senate's summer break starting around August 10, there are only five days left for scheduled sessions before lawmakers adjourn. Stay tuned!

BTC's weekly chart in candlestick format. (TradingView)

The chart depicts the weekly price movements of Bitcoin in candlestick format, with key simple moving averages overlaid. The red and white lines represent the 50- and 100-week averages, while the yellow line indicates the 200-week average.

The 200-week simple moving average (SMA) is being closely monitored by Strategy, the largest publicly traded holder of Bitcoin. The firm points out that Bitcoin has historically traded above this long-term average.

Currently, however, Bitcoin's price is below this average, signaling bearish trends. A recent bearish crossover between the 50- and 100-week moving averages further confirms a downward trajectory. In summary, the prevailing trend remains downwards.
