To transfer crypto, you need to have an address where you can send it. This can be a BCC address if you are using bitcoin, or ETH account if you are using ethereum. You can look for this at your exchange.
Once you have your address set up, here is the way to do it:
Click on send money again and select the amount of BTC/ETH/LTC that you want to transfer. Put in your destination address, go through any additional information required by the recipient (which should only be necessary if they are not eligible for free transfers). Buy some testnet coins first to make sure everything works as intended. Open up one of those addresses with any other supported coin. Send them the same amount of coins that were sent previously, minus fees etc If everything goes well then congrats! I guess now’s your time to buy some shitcoins 😛
