Hi Bitcoiners,
 
I'm proud to announce my exciting website, CoinPrize.com (https://coinprize.com) -- a NASDAQ stock-betting game using bitcoins. All data comes from Yahoo Finance that makes it quite different from many casino games. I would say https://coinprize.com is the fairest game, simply because it solely depends on the NASDAQ data, no server side generated randomness involved, completely provably fair for all players.

It’s also different from casino games because you’re not betting against the host. Instead, you’re betting with the other players who make opposite choices to yours. That means the more people who are betting against you, the more you can win. So invite your friends, and spread the words!

Here’s how it works: For each betting round, given the last close price available at the moment you played, you bet increase or decrease on the close price of the given forecasting date. If the close price of forecasting date is higher or lower than the last close price just like what you predicted, you win.


Pretty much like satoshidice.com, you don't need to register for an account to play and bitcoins are sent back to the original input address when you win. Just start your bitcoin wallet -- let's say bitcoin-qt, for example -- copy the address you are betting on -- say, you bet on GOOG to grow -- then copy the address under the green label "grow address" -- and enter the amount of BTC that you want to bet and send it to that address. There’s a minimum bet of 0.1 BTC and no max bet. The more you bet, of course, the more you win in proportion to the total amount bet by the opposite participants in relation to all winners. Like we said, you win more when more people are betting against you.



Here’s more about the rules:

• Winning a forecast round means the forecast close price rise or fall as what you predicted, and the absolute value of the forecast close https://coinprize.com/promote/img/cp-forecast.png  price minus the based close price https://coinprize.com/promote/img/cp-based.png is larger than $0.01. But if the absolute value is less than or equal to $0.01, host wins. To write it in formula: If |forecast_close_price - base_close_price| > $0.01 you or your opponents wins. If |forecast_close_price - base_close_price| <= $0.01, host wins.
• The minimum bet is 0.1 BTC. Any input that is less than this amount will be returned during that transaction’s payout time. This may take more than 24 hours but less than 48 hours, depending on the time the transaction is being received during the entire betting day.
• There's no maximum bet. The more you bet, the more you win in proportion to the total amount bet by the opposite participants in relation to all winners. If no one bet against you when betting day is closed, you get all your bitcoins back.
• CoinPrize.com as the host will share 19 percent of your winnings excluding your original bet. If you bet 0.3 BTC and have won 1.0 BTC, for example, then you will get 0.3 + 0.81 BTC -- or 1.11 BTC total.

So, I won a bet once and payout was fine.. then I won a bet again yesterday and the payout was supposed to be happening at midnight but I still did not get the payment and it's also not on the website yet?

Got your conversation on facebook, your payout actually has been sent and with 108 confirmations from the network. It's most likely because mcxnow you used is sharing private key or public keys for all accounts. therefore, addresses are shared. Please ask mcxnow for details and prevent using online wallet that are sharing private keys for all accounts.

Yep, issue has been resolved. This website is legit, and has good customer support.
Thanks!
