FSMA oversees smart-contract audits operating in Belgium; only providers authorised under MiCA may serve retail clients. Verify any provider against ESMA’s interim MiCA register.
How is crypto taxed in Belgium?

What payment methods work for buying crypto in Belgium?
The most common rails for retail onramps in Belgium are: SEPA, SEPA Instant, Bancontact.
