Ok, so I guess the 20% is the maximum exposure then? If starting price is $10,000 and you bet it to go up, you really can't profit if it goes higher than $12,000?
Similarly, if you bet it to go down, you can't profit even it it drops under $8,000?
So no incentive to keep pumping it up if it's at $12,000 but it really needs to be at that price at the close of trading if you bet it for 24 hours, and seems like the price opens at 6pm Eastern and closes at 4pm Eastern the following day?
it's still uncertain how this will play out. but the bets are for one month approximately and now you can see why the CEO of international brokers is hesitant to allow trading of this derivative vehicle.
