Strategy, led by Michael Saylor, has acquired nearly 3,000 BTC for $264.1 million, paying an average of $90,061 per Bitcoin. According to NS3.AI, this purchase comes during a period of decline in the cryptocurrency market. The company now holds over 712,000 BTC, with an average cost basis of $76,037 per Bitcoin. Saylor maintains a positive outlook on Bitcoin's future, highlighting reduced supply from miners and increased institutional adoption as significant factors for potential price growth.

0xTodd posted on X. Elon Musk has fulfilled his promise to open-source Twitter's algorithm, providing users with insights into how content is curated and displayed on the platform. This move allows users to better understand what content they are likely to see and how they can effectively express their viewpoints to reach a wider audience.

The algorithm introduces two key concepts: 'Thunder,' representing accounts a user follows, and 'Phoenix Retrieval,' encompassing all Twitter content, including accounts not followed by the user. Additionally, each user has a hidden 'Grok' assistant that predicts engagement with posts and determines whether to display content from Thunder or Phoenix Retrieval.

Twitter's algorithm has evolved from hard-coded rules to a more dynamic system. For instance, in 2023, posts with videos were scored higher, while those with links were penalized. Now, the scoring is less mechanical, focusing on user preferences.

Several overlooked rules impact content visibility. An invisible reputation score, ranging from -128 to +100, is assigned to each user. New accounts start with a low score, limiting their content's reach until they interact positively with high-reputation users. Engaging with low-quality accounts can negatively affect one's score.

The algorithm also addresses 'topic fatigue,' reducing the ranking of multiple posts from the same author within a short period. Repetitive content on popular topics is penalized, encouraging timely posting.

Negative feedback, such as muting or blocking, carries more weight than positive interactions like likes. Extreme behavior can lead to reduced visibility, as one block can outweigh numerous loyal followers.

Verified accounts (Blue V) are favored in the algorithm, making it easier for their content to be retrieved by Phoenix Retrieval. Unverified accounts struggle to reach the initial candidate pool unless their engagement grows rapidly.

Other factors include dwell time, which adds points even if users don't interact with posts, and candidate isolation, where each tweet is evaluated independently. The algorithm avoids recommending repetitive or outdated content and emphasizes the importance of video completion rates.

These insights provide a deeper understanding of Twitter's algorithm, inviting further discussion and exploration.

According to ChainCatcher, CME's "FedWatch" tool indicates a 95% probability that the Federal Reserve will keep interest rates unchanged in January, with a 5% chance of a 25 basis point cut. By March, the likelihood of a cumulative 25 basis point rate cut stands at 20.7%, while the probability of maintaining the current rate is 78.4%. The chance of a cumulative 50 basis point cut is 0.9%.

According to BlockBeats, on January 18, Web3 security platform Immunefi's CEO Mitchell Amador highlighted that nearly 80% of crypto projects that suffer major hacking incidents never fully recover. He noted that most protocols lack awareness of their vulnerability to hacking and are unprepared for significant security events.

Amador emphasized that the initial hours following a breach are often the most destructive. Without a pre-established incident response plan, teams may hesitate, debate next steps, and underestimate the impact of the breach. This period is critical for preventing additional losses.

Due to concerns over reputational damage, project teams often hesitate to pause smart contracts and fail to communicate effectively with users. Silence can exacerbate panic rather than contain the issue. The primary reason for the failure to recover for nearly 80% of hacked projects is not the initial financial loss but the collapse of operational and trust systems during the response process.
