Get your money ready to bet on the increase or decrease in Bitcoin prices without actually buying or selling the cryptocurrency.
That's right starting in 2018 investors can start to create contracts against the rise or fall of Bitcoin prices. It's still unclear if the contracts to bet against the price is on a daily level or not.
I personally think this is a big deal for a lot of people that may not know a lot about cryptocurrencies, blockchains, etc. They can essentially use their money and bet for or against the price increasing or decreasing without having to own Bitcoin.
I can only speculate at this time that individuals looking to bet on Bitcoin prices will have to put a contact in at least 24 hours in advance for a particular day in the future. So one can essentially say on "January 2nd I expect the price to increase" and expect a payout if I am correct.
