It works very similarly to Intrade, just different currency/amounts.

If you put up 1 mBTC long, someone else must put up 9 mBTC short. Or 2 & 8, 2.5 & 7.5, etc.

For any matched bet, there is 10 mBTC between both sides combined. Whoever is correct takes the pot (minus a small fee).


It took me a while to get accustomed to the Intrade/Predictious method, but once you're used to it, you'll be comfortable not only buying shares, but also selling matched (long or short) shares when the odds improve.
