1. Grayscale Forecasts New Bitcoin Highs for 2026 In a report published on Monday, Grayscale Research projected that Bitcoin could reach new all-time highs in 2026, challenging the prevailing market sentiment regarding a multi-year downturn. The analysts explicitly dismissed the validity of the traditional four-year cycle thesis, arguing that the current market structure has fundamentally changed due to institutional capital concentration. Despite Bitcoin's recent 32% correction from its peak, the firm emphasized that drawdowns of this magnitude are common occurrences within broader bull markets. Furthermore, BitMine CEO Tom Lee corroborated this optimistic outlook, predicting that the asset could set fresh records as early as January of next year.

2. Strategy Increases Bitcoin Reserves Amidst Changing Market Dynamics The firm Strategy has acquired an additional 130 Bitcoin for approximately $11.7 million, bringing its total corporate holdings to exactly 650,000 BTC. Concurrently, the company established a new $1.44 billion USD reserve intended to secure dividend payments and interest on existing debt. On-chain analysis indicates a divergence in market behavior; while large "whale" wallets have significantly slowed their accumulation, retail investors appear to be increasing their buying activity during price dips. This shift in accumulation patterns suggests a potential redistribution of assets from institutional to retail holders in the short term.

3. Yearn Finance Secures Partial Recovery Following $9 Million Exploit DeFi protocol Yearn Finance suffered a significant security breach on Sunday, resulting in the loss of approximately $9 million due to an "unchecked arithmetic" bug. The technical team has successfully recovered roughly $2.4 million in stolen assets and confirmed that the vulnerability was specific to the legacy protocol, leaving V2 and V3 vaults unaffected. The attacker utilized a complex method to mint a near-infinite amount of tokens to drain the liquidity pool, marking the third major incident for the protocol since 2021. Security firms are currently conducting a post-mortem analysis to prevent future occurrences of similar high-complexity attacks.

4. South Korea’s Ruling Party Demands Immediate Stablecoin Legislation The ruling Democratic Party of South Korea has issued a strict ultimatum to financial authorities, requiring the submission of a government proposal for stablecoin regulation by December 10. The party aims to pass this legislation by January to establish a bank-led consortium model for issuing stablecoins, thereby protecting national monetary sovereignty. Lawmakers have stated that if the Financial Services Commission fails to meet the deadline, they will unilaterally advance a legislator-initiated bill. This move highlights the urgent political focus on competing with the dominance of the U.S. dollar in the digital asset market.

5. Kalshi Expands Prediction Markets to Solana Blockchain Prediction market platform Kalshi has begun tokenizing thousands of its betting markets on the Solana blockchain to enhance liquidity and accessibility. This strategic expansion aims to compete directly with Polymarket by bridging Kalshi’s regulatory compliance with the decentralized nature of on-chain trading. The initiative follows a record-breaking performance in November, where both platforms saw billions of dollars in trading volume driven by increased retail interest. By integrating with Solana protocols, Kalshi intends to allow users to monetize applications permissionlessly on top of its global liquidity pool.
