Two separate European firms have taken concrete steps to expand their Bitcoin treasuries, signaling a growing trend of corporate BTC accumulation on the continent. BTCS S.A., a publicly listed company on the Warsaw Stock Exchange’s NewConnect market, recently closed a Series F funding round and launched a fresh $100 million offering, while Capital B reportedly raised €15.2 million from global institutional investors specifically to increase its Bitcoin holdings. Both moves highlight a strategic shift where companies treat Bitcoin as a reserve asset rather than a speculative trade, mirroring a playbook pioneered in the U.S. but adapted to Europe’s stricter regulatory environment.
BTCS S.A. differentiates itself through what it calls an Active Digital Asset Treasury Company (DATCO) model, which aims to generate recurring yield from its digital assets without selling them. The company runs validator nodes on two networks: CoreDAO, a Bitcoin-aligned Layer 1 blockchain, and ZIGChain, which powers institutional-grade real-world asset tokenization. These operations require active management, including uptime monitoring, risk mitigation, and protocol security. To support its infrastructure, BTCS has partnered with BitGo for custody and OKX for liquidity and trading access, meeting the standards European institutional investors demand. In March 2026, BTCS entered a liquidity partnership with Hemi, a Bitcoin layer-2 network, committing up to 100 BTC at a backstopped 10% APY for two months (dropping to 6% thereafter), with rewards paid in Bitcoin and USDC. The firm also expanded its market reach by listing on Interactive Brokers and beginning trading on the Frankfurt Stock Exchange, broadening its European investor base.
The broader regulatory context is critical. The EU’s Markets in Crypto-Assets (MiCA) transitional period ends on July 1, 2026, after which any entity providing crypto services to EU clients without a MiCA license will be in breach. BTCS’s publicly listed structure, professional custody arrangements, and disclosures under Article 17(1) of the EU Market Abuse Regulation already align with upcoming compliance requirements. With over $30 billion in real-world assets now tokenized on-chain, BTCS’s validator operations on two chains central to this buildout underscore its positioning.
Meanwhile, Capital B’s €15.2 million raise is explicitly earmarked for Bitcoin purchases, a detail that stands out because it represents a deliberate corporate decision rather than a general-purpose fundraise. A separate CoinMarketCap report suggested the company could add up to 182 Bitcoin to its treasury with the proceeds. However, many specifics remain undisclosed: the exact financing structure, timeline for deployment, acquisition strategy, existing treasury size, and investor identities are not yet public. The move adds to a growing list of firms using dedicated capital raises to accumulate Bitcoin, reinforcing a demand signal that goes beyond ETF inflows or retail buying.
Together, these developments illustrate a maturation of European corporate Bitcoin strategies. While U.S. firms like Strategy (formerly MicroStrategy) rely on convertible notes in a permissive climate, European companies must navigate different capital markets and MiCA’s incoming framework. BTCS’s active infrastructure approach and Capital B’s straightforward accumulation both point to a future where Bitcoin treasuries become a more common balance sheet tool, blending yield generation with regulatory compliance.
