Quick answer
SEPA support is useful for European users who want lower-cost bank transfers instead of card purchases, but availability depends on the exchange, country and account verification level.
What to compare
Check EUR deposit fees, withdrawal fees, processing time, bank compatibility, KYC requirements, minimum limits and whether the same provider supports both deposits and withdrawals.
Safety checklist
Use small test transfers, match account names, keep bank records and confirm the exact exchange bank transfer instructions before sending funds.
