If I receive BITCOIN in my wallet, and then go to a website like: https://shapeshift.io/#/coins, where I can convert bitcoin to ether for example, is this transaction trackable? More specifically, if Party A sends bitcoin from their wallet to my wallet and then I use shapeshift to convert bitcoin to ether and I send that ether back to Party A. Can Party A track the transaction and know that the ether transaction actually came from the original bitcoin transaction?
