When the overall market rises, use [U-based contracts] to short-sell the copycat.
When the overall market falls, buy spot and put it in [currency-based contracts] as margin
Think about it, when the market rises, short-sell the copycat

When the market falls, will the short position make money?
When the market falls, continue to buy spot, and wait for the next round of rise, will you continue to make money?
Is it double profit? Double insurance?
