Prerequisites:

• You already have some BTC

Steps

1. Open the exchange website

   In this guide we'll be using Intercambio.app.
   
   Simply click on "Intercambio.app" to open it.

2. Perform the exchange

   Select the currency you'll be exchanging from on the left, so in this case BTC, and the one you'll be exchanging for on the right, in this case IOTA.
   
   Input the amount of BTC you want to sell for IOTA, paste the receiving address for your IOTA after the trade is done and click "TRADE".
   
   Finally send the amount of BTC to the address that shows up on the screen by either copy-pasting the address shown on the page into your wallet or scanning the QR code on the right.

3. Sit back and wait

   Make sure to note down the Trade ID shown on the page in case of issues with the trade.
   
   Transactions can take a while to complete (often as long as an hour) so be patient.
   
   If you encounter any issues contact Intercambio.app customer support with your Trade ID.
