I have cha in my account but I am betting using btc - I don't see the order book or volume change in poloniex (not when I lost and not when I win a bet).
Here's a more detailed explanation:
When you bet with BTC, we have a server that figures out how much CHA you can buy with the BTC bet on Poloniex, and then creates a special transaction that turns your BTC bet into a CHA bet (crediting your account and debiting ours). The CHA/BTC price you get is exactly what you would get on Poloniex by buying the offers at that exact moment. In fact, our server will generally actually buy those offers at the same time. In this case, we were low on funds, and so you didn't actually see transactions going through Poloniex at the time of your bet. Some of the time, as we're transferring BTC and CHA to and from Poloniex to keep this service up and running, we might not actually buy the offers immediately.
Some time soon we'll update the Technical documentation with these recent changes.

P.S. The exact fee per bet is 0.0000456 BTC.
Just to make sure, even if there is a "fund" with the devs chancecoins for "fast" liquidity for btc bets, in the end all of the chancecoin liquidity is coming from poloniex?
I mean that in no way the devs chancecoin amount is decreasing - right?
