A crypto-desk file this month spent one hour on the chain and six on the off-ramp: the exchange, the fiat rail, the country of settlement and the hour of day. On-chain analytics gets the attention; the off-ramp is where the wallet becomes a person, and that is the record the counterparty file is actually built on.
A person can route through five chains and three mixers and still, at the end, need a bank account in a currency they can spend. That bank account is the part we read. Off-ramp geography is more stable than wallet behaviour because it is bounded by real-world constraints. Licences, correspondent relationships, currency access; wallets are cheap. Fiat exits are not.
The pattern that appears again and again is not exotic. People with real cross-border exposure keep a small number of preferred off-ramps and stay with them. New off-ramps appear at specific moments; a country change, a debanking, a new counterparty, a rule change in the previous exit. The change is the signal; the steady state is the baseline.
For a standing report of any depth, the off-ramp set gets tracked the way banking relationships do. A new one is a note; an old one going quiet is a note. Both together is a paragraph; most weeks there is nothing to add, which is the point.
Clients who ask about crypto exposure usually expect a wallet-focused answer. What they get instead is a map of the fiat perimeter around the crypto activity, because that is the part that generalises and the part that holds up over time.
