Since September 9, 2026, customers of BW-Bank have been able to buy and sell crypto assets through their existing securities account. Access runs through BW Nextbroker, while execution and custody sit with the Austrian provider Bitpanda.

All three answers turn out differently from what the familiar securities-account setting suggests.
