Sure, when in minergate GUI on the wallet page, there is a Changelly message at the bottom of the page. It states "Learn how much you've made in Bitcoins on Changelly". Then when click the link and walk through the pages it shows 1BCN to 10 Ether like you are giving the new user 10 Ether... And nothing in the process tells you it is an example only, until you get to a page that says "confirm and make payment". You even ask for the users ethereum wallet ID like you plan to transfer the $. Just feels a bit shady like you are saying someone earned bitcoin then it feels like you are transferring it over to Ethereum. Guess it's just the marketing approach seems odd.
