When offering financial services in a country, it behooves the vendor to set up a relationship with a local bank. Any legitimate money services business will do this, because otherwise they wouldn't get a single customer. Crypto exchanges don't seem to have this issue because they know their customers are trying to dodge taxes anyway, so they can claim that obstacles to off-ramping to fiat (like having no banks to work with) are a feature.
