Is using a crypto rollup-as-a-service provider legal in Belgium?
Yes. Belgium regulates crypto-asset service providers under MiCA (EU Regulation 2023/1114), enforced from 30 December 2024. FSMA oversees rollup-as-a-service 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?
Tax treatment depends on classification: "good father of the family" (passive) is tax-free, "speculative" gains taxed at 33%, "professional" at progressive rates. Editorial summary, not tax advice: consult a qualified tax advisor in Belgium before filing.
What payment methods work for buying crypto in Belgium?
The most common rails for retail onramps in Belgium are: SEPA, SEPA Instant, Bancontact.
Are international platforms (Coinbase, Kraken, Binance) available in Belgium?
Coinbase and Kraken hold MiCA authorisation valid in Belgium. Binance does not: no Binance entity is on ESMA's register (read 10 November 2026); every transitional period ended by 1 July 2026, so none covers it there.
