My service lets you create your own bitcoin price predictions and bet on these predictions instantly. At predictbits, you won't need to wait for a moderator to approve your prediction. You also won't need to wait for them to approve your payout. All of this is done programmatically. Our IRC bot, widget and API allows site owners, channel operators and developers to advertise for a referral commission. I hope this will bring action to a lot of crazy predictions and earn you some bitcoin.

I made predictbits after seeing speculators spam their predictions on IRC and reddit. I wanted to give all of these people a place to put their money where their mouth is and eliminate the nonsense spam on forums that I frequent. After sharing my idea with on google hangouts with people from #bitcoinmarkets, I decided to go forward with predictbits. I hope you guys will find this useful when you want to silence a troll or bet against a friend.

How it works:

• Make predictions about whether the price will be higher or lower than your target at a certain time in the future.
• Bet bitcoin on that prediction
• Anyone else can call your bet. whoever is right takes the bitcoin. We determine winners with Bitstamp's ticker
• 10% of losers bets goes to the site.

Things to note

• If any of your bet uncalled, you receive that wager back
• We pull our price data from Bitstamp
• The time window to bet closes 2 hours before a prediction concludes

• Payouts are sent in chronological order until no remaining bitcoin could be matched. We are not parimutuel.
