1. Go to Wallet → Buy crypto (or Sell crypto).
2. The system shows the live quote (buy/sell exchange rate), calculated from the market plus the platform's margin.
3. When you confirm the amount, a quote valid for 120 seconds is issued. If you take longer to confirm the operation, you will have to request a new quote.
4. To buy: the BOB amount is deducted from your available fiat balance and USDC is credited.
5. To sell: the USDC is deducted from your available crypto balance and BOB is credited.
6. The operation may execute automatically and immediately, or be queued for manual processing by the team if the amount is very large, depending on the platform's reserve availability at that moment. This is transparent to the user: the only visible effect is a longer delay on large amounts.
If you need to lock a price for several hours instead of 120 seconds, use an OTC operation.
