According to PANews, a report from Miner Weekly highlights significant challenges in the Bitcoin mining industry due to a sharp decline in profitability. In November, Bitcoin experienced a substantial price correction, causing the revenue per unit of hash power to drop from $55 to $35 per PH/s. This figure is now below the median total cost of approximately $44 per PH/s for publicly listed mining companies. The global hash rate is nearing 1.1 ZH/s, resulting in a payback period for the latest mining machines exceeding 1,000 days, which is longer than the countdown to the next halving event. In response to these challenges, companies like CleanSpark have repaid their Bitcoin-backed loans and raised over $1 billion in financing. Additionally, Cipher and Terawulf have collectively secured over $5 billion in funding during the fourth quarter. Many mining companies are shifting their strategies towards deleveraging and maintaining liquidity as the industry enters a new phase of survival selection. This trend reflects the growing pressure on miners to adapt to the evolving economic landscape and ensure their long-term viability.

According to ChainCatcher, South Korea's largest cryptocurrency exchange, Dunamu Inc., is set to be sold to the fintech division of Naver Corp. Founders Song Chi-hyung and Kim Hyoung-nyon agreed to the all-stock transaction last week. Bloomberg Billionaires Index reports that in this $13.6 billion merger, Song Chi-hyung will receive a 19% stake in the combined entity, valued at $2.7 billion, while Kim Hyoung-nyon will obtain a 10% stake, worth $1.4 billion. This deal propels both founders into the ranks of the world's wealthiest individuals.

According to ChainCatcher, the Acting Chairman of the U.S. Federal Deposit Insurance Corporation (FDIC), Travis Hill, announced in testimony to the House Financial Services Committee that the FDIC plans to introduce its first regulatory proposals for stablecoin issuers. These proposals aim to implement the U.S. Stablecoin National Innovation Guidance and Establishment Act (GENIUS Act). The initial set of rules will outline the process for stablecoin issuers to apply for federal regulation, with further prudential requirements for FDIC-regulated payment stablecoin issuers, including capital standards, liquidity requirements, and reserve asset quality oversight, expected early next year. The FDIC, along with the Treasury Department and other agencies, is advancing its regulatory responsibilities under the GENIUS Act. The proposed rules will undergo a public comment period before being finalized. Hill also mentioned that the FDIC is developing additional guidance on the regulatory status of 'tokenized deposits' based on recommendations from the President's Working Group on Financial Markets. The hearing will also include testimonies from other financial regulatory bodies, such as the Federal Reserve. Federal Reserve Vice Chair for Supervision, Michelle Bowman, stated that the Federal Reserve is working on a regulatory framework for stablecoin issuers, focusing on capital, liquidity, and risk diversification, as required by the GENIUS Act.

According to ChainCatcher, Federal Reserve senior bank regulator Michelle Bowman is set to announce plans for new regulatory rules for banks and stablecoins during a hearing at the House Financial Services Committee on Tuesday. The initiative aims to foster healthy competition among traditional Wall Street financial institutions, fintech companies, and cryptocurrency enterprises. In her prepared remarks, Bowman emphasized the responsibility of regulators to encourage innovation responsibly while enhancing oversight of potential safety and soundness risks associated with such innovations.

However, he emphasized that fundamentals such as wallet numbers, on-chain activity, fees, and asset tokenization are showing signs of improvement. Lee believes that the divergence between price corrections and fundamental progress is making the risk-reward profile of BTC and ETH more appealing.

According to BlockBeats, Bloomberg ETF analyst Eric Balchunas announced on social media that global asset management giant Vanguard will allow trading of ETFs and mutual funds tracking Bitcoin and other cryptocurrencies on its platform starting tomorrow. Balchunas noted that these ETFs have been tested during various volatile periods and have performed as expected.
