Pro Tips for Using Mercado Bitcoin with Casinos
- Complete full KYC verification immediately after creating your account — don’t wait until you want to withdraw
- Enable 2FA before your first BTC purchase to avoid delays when you’re ready to send
- Use Quick Buy for casino deposits — it’s the fastest option and the small price premium vs. a limit order is usually negligible for deposit amounts
- Buy slightly more BTC than your intended deposit to account for the network withdrawal fee
- Save your casino’s deposit address carefully, but always generate a fresh address for each transaction (some casinos rotate addresses)
- Time your purchases — use the zero-fee 48-hour window for new accounts, and consider buying during lower Bitcoin network fee periods
- Keep records of all transactions for Receita Federal tax reporting (required for crypto transactions exceeding R$35,000/month)
- Consider using the MB Pay digital account for faster Pix integration if you’re a frequent depositor
