This is an exchange into XMR, not a change to the privacy properties of an existing Bitcoin balance. Bitcoin remains the source network. Monero is the receiving network. Keeping those two ends separate is the useful starting point for the page.
The funny name on the header has no opinion about your wallet backups. The practical route is straightforward: select BTC, select XMR, inspect the amount, validate the receiving details and keep the order reference. Every instruction that controls the actual transfer comes from the provider’s current exchange flow.
01/A converter number is only the beginning
An indicative BTC/XMR ratio cannot create a deposit address or reserve liquidity. The form calculates a route for your chosen amount and applies the provider’s current conditions. Review the quoted XMR output, any stated expiry and the deposit amount before you move anything from your Bitcoin wallet.
02/Bitcoin source, Monero destination
Your source wallet broadcasts a Bitcoin transaction to the deposit address provided for this exchange. Your Monero wallet supplies the receiving details for the output. Do not send BTC directly to a Monero address, and do not reuse a Bitcoin deposit address from an unrelated order because the same ticker appears.
03/Save the references you can actually use
Keep the provider’s exchange ID and the Bitcoin transaction reference after sending. They are useful for checking an observed deposit and discussing an order with the provider. Avoid submitting another full deposit just because a status screen takes time to refresh or a receiving wallet has not updated yet.
