In mid-2022, an attack on OpenSea's email service provider, Customer.io, led to the leakage of over seven million user email addresses. This data, which was not initially made public, has now been fully publicized, according to SlowMist's chief information security officer, 23pds. The leaked information includes emails of prominent figures in the cryptocurrency sector, providing scammers with a new resource for phishing and scamming. OpenSea had previously warned its customers about the breach, advising them to assume their email was compromised and to take precautionary measures. The incident underscores the ongoing threat of phishing scams, which were reported to have cost over $1 billion in stolen digital assets in 2024. Users are recommended to use strong, unique passwords, employ two-factor authentication, and keep their software updated to mitigate risks associated with such data leaks.

Summary
The bitcoin mining ecosystem has hit a new peak with the mining difficulty adjustment soaring to 110.45 trillion, marking it as the eighth consecutive positive adjustment. This escalation in difficulty intensifies the competition among miners, making it increasingly challenging to mine new blocks and earn bitcoin rewards. As a result, some publicly traded mining companies have begun to explore alternative revenue streams in high-performance computing and artificial intelligence, unable to sustain operations solely through bitcoin mining. Notably, MARA Holdings has also ventured into issuing convertible bonds to acquire more bitcoin and optimize revenue through lending. Historical data shows mixed outcomes following such difficulty adjustments; for instance, after the China mining ban in 2021, bitcoin experienced a bull run followed by a bear market, while in 2018, similar adjustments preceded both market highs and lows. Despite these fluctuations, the network's hashrate remains robust, currently at 775 EH/s, with projections suggesting it could reach 1 zettahash per second before the next halving.

Summary
Bitcoin's reserves on exchanges have dwindled to levels not seen since June 2018, with only 2.35 million BTC available as of January 13, according to CryptoQuant data. This decline is largely attributed to institutional investors, including hedge funds, who are capitalizing on the current dip in Bitcoin's price. André Dragosch from Bitwise highlighted that hedge funds are increasing their exposure to Bitcoin, suggesting a potential supply shock if demand continues to outstrip the available supply. Despite this, Bitcoin's recovery to surpass the $100,000 mark is hindered by low trading volumes, as noted by Ryan Lee from Bitget Research. The broader cryptocurrency market also reflects this trend, with trading volumes at their lowest since before the U.S. elections, indicating a lack of market excitement. However, analysts remain optimistic, predicting Bitcoin could reach a cycle top above $150,000 by late 2025, driven by an expected increase in global money supply.

Summary
Laser Digital, the digital asset subsidiary of Nomura, predicts that 2025 could be a significant year for cryptocurrency exchange-traded funds (ETFs) in the U.S. The report highlights that over twelve crypto ETFs might be launched if approved by the SEC, with asset managers having already submitted twelve filings. These potential ETFs include innovative products like a ProShares ETF that tracks the S&P 500's return in bitcoin, a combined bitcoin/ether ETF, and ETFs based on litecoin, XRP, and Solana. The report suggests that a bitcoin/ether ETF is most likely to receive approval first. The success of spot bitcoin ETFs in the previous year, exemplified by Blackrock's iShares Bitcoin Trust, which amassed $53 billion in assets, underscores the potential for these new ETFs. The regulatory environment is also expected to become more favorable with the appointment of Paul Atkins as SEC chairman and the anticipated support from a crypto-friendly administration under President-elect Donald Trump.
