# This Week in Crypto: adoption expands as infrastructure strengthens > This week in crypto, Bitcoin adoption expands, Strategy marks its 100th purchase, Ethereum plans faster finality, and Jane Street faces Terra lawsuit claims. News · 3 min read Published 27 February 2026 This week in crypto, the gap between price performance and real-world adoption remained a clear theme. While [Bitcoin](/buy/btc/) continues to trade below its previous highs, institutional involvement, corporate treasury strategies and core blockchain development are all moving forward. From renewed buying by major public companies to legal action tied to past collapses and ambitious upgrades to [Ethereum](/buy/eth/), the industry continues to evolve beneath the surface. The top story centres on Bitcoin’s accelerating adoption across institutions, banks, public companies and even nation-states. Recent reporting showed that institutional investors accumulated significant amounts of BTC last year, even as prices cooled. At the same time, a growing number of major US banks are developing Bitcoin-related products as regulatory clarity improves. This expansion is happening more quietly than in previous retail-driven bull markets. Bitwise CIO Matt Hougan reinforced this point, arguing that many traditional investors still underestimate the long-term impact crypto could have on financial markets. In his view, the real opportunity lies in understanding how tokenised assets, stablecoins and blockchain-based payment and settlement systems may reshape finance over the coming decade, rather than focusing only on short-term price swings. In macro and institutional developments, Strategy reached a major milestone, announcing its 100th Bitcoin purchase since first adopting a BTC treasury strategy in 2020. The company added to its holdings again this week, extending a streak of weekly acquisitions in 2026, even with Bitcoin trading below its overall average purchase price of US$76,020 per coin. What began as a US$250 million allocation has grown into the largest public corporate Bitcoin treasury in the world. Strategy’s consistency continues to influence other firms considering similar approaches, reinforcing the idea that some corporations now view Bitcoin as a long-term reserve asset rather than a short-term trade. On the regulatory and policy front, attention returned to the collapse of the Terra ecosystem. Jane Street, a large global trading firm known for market-making and quantitative trading across traditional and digital asset markets, was sued by the court-appointed administrator overseeing Terraform Labs’ bankruptcy. The lawsuit alleges that Jane Street engaged in insider trading that worsened the 2022 collapse, claiming the firm executed major trades shortly after Terraform withdrew liquidity from a key trading pool without public disclosure. Jane Street has denied the allegations, calling them baseless. While the case will play out in court, it has reignited broader discussion around transparency, market structure and the role of sophisticated trading firms during times of market stress. In the Web3 and decentralised applications sector, Ethereum’s roadmap attracted significant attention. Co-founder Vitalik Buterin outlined plans to reduce [Ethereum](/buy/eth/)’s slot time, the time between blocks, from around 12 seconds to roughly two seconds. This would make the network feel faster and more responsive. More importantly, the proposal aims to reduce transaction finality, which is the point at which a transaction is considered irreversible, from around 16 minutes to a target range of six to 16 seconds. This would improve user experience and strengthen Ethereum’s role as infrastructure for decentralised finance and tokenised assets. The roadmap also includes quantum-resistant design considerations to help future-proof the network. Quantum computing also entered the conversation from a [Bitcoin](/buy/btc/) perspective. Strategy executive chairman Michael Saylor stated that a credible quantum threat to Bitcoin is likely more than ten years away. He suggested that if such a risk were ever to emerge, coordinated global upgrades across digital systems would be expected. While the timeline remains debated, the discussion highlights how long-term cryptographic resilience is becoming a mainstream consideration for both Bitcoin and Ethereum. Overall, this week underscored a familiar but important dynamic. Market prices may fluctuate, but adoption, infrastructure development and institutional participation continue to move forward. Corporate treasuries are expanding, legal accountability is being tested, and core blockchain networks are evolving. As the industry progresses through another consolidation phase, the structural foundations of the crypto economy appear to be strengthening rather than stalling. **More news stories circulating the block:** - Nasdaq files to list VanEck’s[Jito](/buy/jto/) SOL ETF - [Aave](/buy/aave/) tops US$1T in lending, a DeFi first - Ex-[Chainlink](/buy/link/) staff joins SEC’s crypto task force - NVIDIA reports record US$68.1B Q4 revenue About the editorial team The Digital Surge Editorial Team Our editorial team writes and reviews Digital Surge’s news, insights and crypto guides, pairing plain-English explanations with the practical experience of running an [Australian cryptocurrency exchange](/about-us/).
