There is a future on Rollbit that allows that, it gives you the option to place bet on either the market would go down towards the bears or up towards the bulls. I think that’s what you are looking for and yeah, you can set the multiplier that would apply when the market moves towards your predicted direction.
When you open the Rollbit.com casino, click on futures and be sure to read the instructions that follows to familiarize yourself with the space and enjoy gambling.
Thanks a lot! But when you're betting against the bookmaker (in this case, the casino), the odds are usually not that attractive.
That’s why a prediction market - where you’re betting against the crowd - would be much more useful here.
I think that when you’re placing a bet not to profit, but to hedge a trading position, there are situations where the hedge could be very cheap.
