THORChain halted trading on Friday morning following a cross-chain exploit estimated at over $10 million across Bitcoin, Ethereum, BNB Smart Chain, and Base. RUNE fell about 10% within hours to $0.52 as the team also stopped on-chain signing as a precautionary step.

Starting March 30, 2026, BNP Paribas will let retail clients in France access six Exchange Traded Notes (ETNs) linked to Bitcoin and Ether through ordinary brokerage accounts. The products provide price exposure without direct token ownership, while carrying issuer counterparty risk and operating under MiFID II rules. The rollout highlights a widening gap with Italy, where Consob still restricts retail distribution of crypto ETPs.

Between late February and late March 2026, rising US-Iran tensions and an oil shock alongside a Fed pause at 3.50%–3.75% kept Bitcoin trading in a broad band. BTC swung roughly from $63,000 to $74,000 and ended March around $66,000–$67,000, raising fresh debate over whether it behaves like a crisis hedge or a liquidity-sensitive risk asset.

DeFi entering 2026 is described as moving from experimentation to infrastructure, with Total Value Locked estimated at $130–$140 billion and capital increasingly concentrating in a small set of major protocols. The piece outlines four pillars—Aave-led lending, EigenLayer restaking, yield-bearing stablecoins, and evolving DEX routing—while flagging Ethereum concentration, regulatory uncertainty, and exploit losses that reached about $2 billion in 2025.

On March 17, 2026, the SEC and the CFTC jointly issued a 68-page interpretive document saying Bitcoin, Ethereum, Solana, XRP and 12 other major tokens are digital commodities rather than securities. The document also states that four main staking models and no-consideration airdrops are no longer treated as securities transactions, shifting primary oversight for the covered assets to the CFTC.

On March 18, 2026, the European Commission unveiled EU Inc., an optional pan-European corporate regime dubbed the "28th regime". The proposal would allow founders to register a company online within 48 hours for under €100, with a minimum share capital of €1. If approved by the European Parliament and the Council, it targets becoming operational by end-2026, with first companies potentially forming around 2027.

Failing to declare crypto holdings or gains already triggers fines, capital freezes and automated checks, with stricter rules starting on 1 January 2026. Penalties range from 3%–15% for non-monitoring and 90%–120% of the tax due for undeclared profits, while banks require proof of fund origin. Under MiCA, exchanges share user data with authorities, and the capital gains rate will move to 33%.
