Do you guys ever go to a restaurant, to a store, or to do groceries?

This places offer you goods and services that you pay for and they get a cut for doing the work of prep everything for you.

You go to Chipotle, you buy a burrito and I don't think you care what they do with their profits while you get your burrito to eat.

Exchanges are the exact same, no difference. Another thing is if after that, you expect the exchange to give you a yield, a credit card or dance flamenco for you, they are not what they are here for.
