Pundi AI has announced a collaboration with LinqAI, the development team behind the decentralized computing network LinqProtocol, to jointly build a decentralized AI ecosystem driven by trusted data and scalable computing power. Pundi AI enables the community to create and validate high-quality AI training data through on-chain traceability and tokenized ownership, while LinqProtocol provides global GPU and CPU resources through a permissionless computing network, running AI tasks at a lower cost than centralized cloud computing. This collaboration will combine Pundi AI's verifiable datasets with LinqProtocol's computing network to unlock new use cases requiring high-intensity computing, such as advanced AI agents, inference workloads, simulations, and automation. The shared vision is to empower users to control the value they create, with data belonging to the generator, and computing power transparent and globally distributed. In the future, as both ecosystems expand, more integration, incentive mechanisms, and developer opportunities will be introduced to jointly build a community-driven, open-network-supported AI future.

According to BlockBeats, Jocy, founding partner of IOSG, shared insights on social media regarding the evolving dynamics of the crypto market. Jocy highlighted 2025 as a pivotal year marked by a fundamental shift from retail speculation to institutional allocation. This transition is evidenced by core data showing institutional holdings at 24% and a 66% exit by retail investors, indicating a completed turnover in the crypto market. Despite a 5.4% decline in Bitcoin's value in 2025, the cryptocurrency reached a historic high of $126,080 during the year. The market leadership has shifted from retail investors to institutions, who continue to build positions at high levels, focusing on cycles rather than prices. While retail investors are selling, institutions are buying, marking the current period not as a bull market peak but as an institutional accumulation phase. Looking ahead to 2026, the midterm elections in November are expected to influence market dynamics. Historically, election years prioritize policy, suggesting that the first half of 2026 may be a policy honeymoon period favorable for institutional allocation and market optimism. However, the latter half of the year may see increased volatility due to political uncertainties. Risks include potential delays in market structure legislation, continued selling by long-term holders, and uncertain election outcomes. Yet, these risks also present opportunities, as periods of pessimism often offer the best chances for strategic positioning. In the short term (3-6 months), Bitcoin is anticipated to fluctuate between $87,000 and $95,000, with institutions continuing to accumulate. In the medium term (first half of 2026), policy and institutional drivers could push Bitcoin's target to between $120,000 and $150,000. In the long term (second half of 2026), increased volatility is expected, influenced by election results and policy continuity. The year 2025 signifies an accelerated institutionalization of the crypto market. Despite negative annual returns for Bitcoin, ETF investors have demonstrated strong holding resilience. The year is characterized by the largest supply turnover, robust institutional allocation intentions, clear policy support, and extensive infrastructure development. Although Bitcoin's price fell by 5%, ETF inflows reached $25 billion, indicating optimism for the first half of 2026. Key considerations for 2026 include legislative progress on market structure bills, potential expansion of strategic Bitcoin reserves, and policy continuity post-midterm elections. In the long term, improved ETF infrastructure and regulatory clarity are expected to lay the groundwork for the next market uptrend, as traditional valuation logic becomes obsolete and new pricing power is established.
