“Can a self-custodial crypto wallet replace the four-tool stack (wallet + exchange + bank + card) that keeps Bitcoin out of everyday spending?”
Founded 2015 as a Bitcoin-native payments and remittance service in Berlin, Bitwala evolved into Germany's early 'bank for the blockchain economy,' offering a current account with an embedded BTC wallet on top of solarisBank rails. Rebranded to Nuri in 2021 to broaden appeal, then collapsed into insolvency in 2022 after crypto-market and counterparty (Celsius) exposure. Returned to the Bitwala brand in late 2023 with a fundamentally different thesis: self-custodial MPC wallet with no seed phrase, keys held by the user, paired with a Visa card and IBAN — collapsing wallet/exchange/bank/card into one product where custody stays with the customer.
