Banking and Bitcoin coexisting in the same account felt like a contradiction in terms for most of the 2010s. Banks were systematically closing accounts connected to crypto activity while the crypto industry was building parallel financial infrastructure that deliberately avoided the banking system. Bitwala was founded in Berlin in 2015 to bridge that gap — building a bank account with integrated Bitcoin functionality, letting users hold euros and Bitcoin in the same place and convert between them instantly. The product was genuinely novel: a German IBAN, a Visa debit card, and a Bitcoin wallet under one roof, with the regulatory standing of a licensed German financial institution. Bitwala rebranded to Nuri in 2021, reflecting a broader evolution from a Bitcoin-specific product toward a more comprehensive crypto banking platform. The Nuri brand subsequently entered insolvency in 2022, a casualty of the crypto market downturn and the difficult economics of building a consumer banking product. The Bitwala/Nuri story is one of the more instructive in European crypto banking — a genuinely innovative product that proved the market wanted crypto-integrated banking accounts, but that couldn't build a sustainable business model before the market turned.
