One of the easiest ways to transform any token into dollar exposure is perpetual swap contracts. For example, Bitmex offers a BTC/USD contract that is margined in BTC. This contract is structured like non-linear inverse future contracts, meaning the contract value is measured in one currency, USD, but the position is margined and settled in a different currency, BTC. If a user opens a 1x short position, this gives the user a dollar exposure with the ability to earn yields from funding payments. This way of hedging is in fact widely adopted by traders to get exposed to dollar exposure.
