Zurich Cantonal Bank (ZKB), Switzerland's largest bank, has announced that its customers can now use bitcoin and ether trading and storage services using the ZKB mobile application and its electronic banking platform. Alexandra Skriba, head of ZKB's Institutional Clients department, said that ZKB takes over the most important function of securely storing private keys. Therefore, customers and third-party banks do not need their own wallet, and they do not need to worry about storing their private keys. To work with digital assets, Zurich Cantonal Bank has teamed up with Crypto Finance, which has received a license to provide crypto services from the Swiss financial regulator FINMA. I think this will be else one bost for crypto market development.
