Tether was actually created to solve the problem you describe. Traders needed to be able to sometimes park assets in dollars with an exchange (if they're exiting a position for example), but couldn't because of US regulations, so Tether was created and has been wildly successful. And it's interesting how much hate it continues to get, especially from people in the US. It was released in 2014 and has maintained it peg since then, with trillions and trillions of dollars of value transacted in it. It's one of longest running and most successful crypto projects by far.
