DZ Bank, the central cooperative bank in Germany, has started a trial of retail cryptocurrency solutions with the first bank, Westerwald Bank, by opening a cryptocurrency wallet and starting trading. Other partner banks are expected to go online by 2025, but the specific time depends on each institution. In March, DZ Bank partnered with the Stuttgart Stock Exchange (Börse Stuttgart) to provide its customers with retail cryptocurrency trading and custody services. DZ Bank serves 737 community banks (known as Volks and Raiffeisenbanke).
