A subsidiary of the Stuttgart stock exchange, blockcknox GmbH, has been holding Bitcoin and Co. for private investors since the beginning of last year. The services of blockcknox are now to be offered to an institutional clientele. The reason for this is the regulatory clarity that has been in place for crypto-custodians in Germany since 1 January this year. Users of the trading app Bison, a product of the Stuttgart stock exchange, have been able to participate in crypto transactions in a regulated environment for some time now, i.e. buy and sell Bitcoin and Co. The subsidiary keeps them in safe custody. In September 2019, the token trading platform was opened for selected customers. The ambitious goal: BSDEX is to become the leading trading place for digital assets such as Bitcoin and security tokens in Europe.
