I would go with funding arbitrage strategy. If longs pay shorts, you go short on futures (use as little leverage as possible to make sure you wont be liquidated) and at the same time you buy on spot with the same position size. You are net 0, so you are not exposed to currency risk (as long as you will not get liquidated) but you earn on funding and price spread (very often when there is a big funding there is also big price spread)
