We're not permitted to make speculative statements about the potential returns from using COIN, but the rewards are in the form of XYO, a type of ERC-20 utility token used for the purpose of location verification and traded privately on cryptocurrency exchanges.
By holding crypto, you have the option of trading these tokens for USD or your preferred currency at a later date whenever you choose.
You can check your favorite ERC-20 token exchange and see the current value of XYO or any of these tokens on that exchange if you like.
