As of March 10, 2026, Bitcoin developers are advancing BIP-360, a proposal that adds Pay-to-Merkle-Root outputs to cut down on quantum-exposed public keys by removing Taproot’s key path spending. The change preserves existing smart contract flexibility via Tapscript Merkle trees but does not introduce post-quantum signature schemes or automatically protect legacy coins. Instead, it marks an incremental step in a multi-year migration strategy toward stronger quantum resilience across wallets, exchanges and custodians.

In 2025, SEC disclosures showed that Peter Thiel-linked Founders Fund unwound its entire 7.5% position in Ether treasury company ETHZilla after the firm sold 24,291 ETH to meet debt obligations. ETHZilla had previously raised $425 million, pursued a large Ether reserve with over 100,000 ETH and relied on leverage, exposing structural vulnerabilities amid price volatility. The move highlights the operational and balance sheet risks of debt-fueled Ether treasury strategies compared with simpler Bitcoin-focused models.

Intercontinental Exchange, the parent of the NYSE, has outlined a blockchain-based platform focused on tokenized securities, onchain delivery‑vs‑payment settlement and 24/7 funding via stablecoins. The effort targets post‑trade processes such as reconciliation and collateral mobility, aiming to cut counterparty risk and operational delays, subject to regulatory approval.

Pig-butchering crypto scams cultivate long-term trust, then funnel victims into fake digital asset platforms. In January 2026, losses reached $370.3 million, with social engineering accounting for about $311 million. Authorities are pursuing networks and laundering operations, but cross-border structures and encrypted channels complicate enforcement.

In February 2026, Polymarket filed a federal lawsuit in Massachusetts arguing that its event contracts fall under the exclusive jurisdiction of the CFTC rather than state gambling laws. The outcome could determine whether prediction markets like Polymarket and Kalshi face a single national regulatory framework or a patchwork of state-level rules governing activity across the United States.

Address poisoning is a scam that tampers with a user's transaction history instead of attacking private keys, convincing victims to send funds to a maliciously crafted lookalike address. Incidents including a roughly 3.5 wBTC theft from a Phantom Chat phishing campaign in February 2026 and a $50 million USDT loss in 2025 show how interface design and user habits can lead to large losses. By abusing dust transfers, copy buttons and truncated address displays, attackers exploit behavior and wallet UX to make poisoned addresses appear trustworthy.

Claims of being Satoshi Nakamoto must be resolved by cryptography, not publicity. Conclusive proof requires a publicly verifiable signature from a private key linked to early Bitcoin addresses, ideally from 2009, or an onchain move from those dormant coins. Courts, documents and code are insufficient, and a UK High Court ruled Craig Steven Wright is not Satoshi.

In 2026, investors are repricing scarcity across Bitcoin, gold and silver by emphasizing narratives, market access, liquidity and portability. Bitcoin's fixed issuance now meets ETFs and derivatives, while gold's trust and collateral role and silver's industrial pull create distinct signals. This reframing influences pricing, hedging behavior and how capital circulates among scarce assets.

As of Dec. 30, 2025, the Financial Times said the rial had lost more than 40% of its purchasing power since June, falling to roughly 1.4 million rials per US dollar. Amid banking failures and political fallout, public debate in Iran turned to Bitcoin as a potential exit option beyond domestic monetary controls. Yet volatility, legal risk and uneven access curb broad adoption.
