You can pay the fee with Bitcoin, it's a choice when making your bets. Three reasons for the credits.

(1) We can sell them cheaper in bulk (see the credits purchase page for amounts, though the details there may change) so the fee goes down if you opt to do it.

(2) It saves on network fees to not transmit us a fee before each offer or bet - since we collect up front instead of after betting (done in this order to avoid offer spam as I mentioned earlier)

(3) We wait for 2 confirmations if you pay the fee with Bitcoin directly. That takes ~20 minutes. The quicker an offer goes up to the site the more chance that a better will see it and take the offer up. for someone making lots of bets I'm sure it's a nice feature to get your bets up instantly (or nearly instant, backend processes it first).

Also a minor one (4) we can give away credits to people that we like so they can play free! You can get some in our IRC channel during the beta.

Edit: oh i kinda misread what maku said. The thing that's awkward is trying to collect a fee and then making multisig addresses to pay in to. So you currently can't just pay fee + pay-in in the same transaction on our site. This is one of the weaker parts of the system and I'm not entirely sure there's a great fix. If I open it up and let everyone post offers I fear very few would actually be serious.


Agreed! I'm even having trouble explaining it here and we're supposed to be the Bitcoin experts around here haha. The more I think about it the more I want to make an Electrum plugin to make this easy.
