> a reasonable metric for someones main bank, especially in today's cashless society In Europe, the primary region for Revolut at the moment, cashlessness is highly variable. In a country like the UK or The Netherlands, DAU might be a reasonable measure but in say Germany, which is largely still cash-based, it's less relevant. I'd say MAU or something like that makes more sense for a predominantly European financial service (Revolut is not a bank, it does not offer bank accounts).
