Why did my bank decline the payment to an exchange?

Usually a bank-level block on crypto merchants, not a legal problem and not the exchange refusing you.

Card networks tag crypto purchases with their own category code, and many banks block that code by default. Transfers get similar treatment: some banks decline them, some hold them for a phone call, some allow them and flag the account.

This is a decision each bank makes for itself. It is not a law, it changes without notice, and it varies between two accounts at the same bank.

What usually helps: calling the bank and confirming you intended the payment, using a bank transfer instead of a card, or using a platform that supports the local instant transfer system rather than an international wire.

What does not help: trying again repeatedly, or accepting an offer from anybody who contacts you afterwards claiming they can "process" it for you.
