When Zürcher Kantonalbank launched crypto custody and trading in early 2024, the bank modeled its expected client base around younger retail investors. The actual demographic surprised everyone. Average crypto buyers at ZKB sit between 30 and 50 years old, predominantly male, and concentrated in private banking rather than retail accounts. More than 40% had no investment portfolio at the bank before opening a crypto custody account — their cash had been sitting idle, and crypto was the product that converted them from depositors into investors. "This is probably the biggest surprise of this launch. We expected, like many others, to attract a very young clientele. That's not the case at all," ZKB Head of Digital Assets Peter Hubli told The Big Whale.
That demographic finding has implications that extend well beyond Switzerland.

The narrative that crypto adoption is primarily a young retail phenomenon has shaped how most traditional financial institutions have thought about whether and when to offer digital asset services — treating it as a product for a future client base rather than a current one. ZKB's data suggests the actual demand sits in the 30 to 50 age range, among people with existing financial sophistication and idle capital looking for a regulated, bank-grade way to access an asset class they already want exposure to. The 40%-plus figure of new portfolio clients is particularly striking: crypto is not just serving existing bank customers with a new product, it is actively converting non-investors into active portfolio holders. For any bank still treating crypto as a niche offering for a demographic segment they do not yet serve, the ZKB experience is a direct challenge to that framing.
