Is using a crypto identity provider legal in Spain?
Yes. Spain regulates crypto-asset service providers under MiCA (EU Regulation 2023/1114), enforced from 30 December 2024. CNMV oversees decentralised identity operating in Spain; only providers authorised under MiCA may serve retail clients. Verify any provider against ESMA’s interim MiCA register.

Capital gains taxed in tiers: 19% up to €6,000, 21% to €50,000, 23% to €200,000, 27% to €300,000, 28% above. Form 721 declares foreign-held crypto over €50,000. Editorial summary, not tax advice: consult a qualified tax advisor in Spain before filing.
What payment methods work for buying crypto in Spain?
The most common rails for retail onramps in Spain are: SEPA, SEPA Instant, Bizum.
Are international platforms (Coinbase, Kraken, Binance) available in Spain?
Coinbase and Kraken hold MiCA authorisation valid in Spain. 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.
