Having a deposit available immediately, and deferring cashouts until the desired number of confirmations would increase playability immensely without risking double spends, yea?

People say that, but I don't see how it's safe.

How do you defend against:

* attacker deposits 1 BTC
* bets it all
* wins 1 BTC
* waits for confirmation
* withdraws

* attacker deposits 1 BTC
* bets it all
* loses 1 BTC
* double-spends, effectively cancelling the deposit
* can't withdraw, but doesn't need to - the deposit never happend

In the first situation, the site is down 1 BTC.
In the second situation, the site breaks even.

Net result: site loses 1 BTC.

Waiting for 1 confirmation before you start playing isn't such a hardship, and even has the benefit of acting as a 'cooling off' period in which the player can decide if they really want to gamble.

tldr: the attacker only double spends when he loses, and in that case there's nothing *to* withdraw

A small thing that I don't like is the fact that when you try to change the profit or the multiplier it changes the bet size and I don't like this.

Are you sure?  I can't reproduce this.  When I set a bet size then edit the multiplier or chance, the bet size stays the same and it's the profit that changes, which is to be expected.  As the multiplier changes, so does the profit.

Perhaps you can walk me step-by-step through how to see the problem?

Bet size: 1.0000
Profit: 2.0000

Now, I edit "profit" to 1.5:

Bet size: 1.5000
profit: 1.5000

Oh, I see.  I read it as 'chance or multiplier' he was changing, not 'profit or multiplier'.  It's been another long day...

I think if you change the multiplier it doesn't affect the bet size, but changing the profit does.  It's got to change something.  I was thinking of it as you set the odds you want, then type the profit you need and it will tell you how much to bet.  But I guess the more common use case is "I have 4 BTC, I need 2 BTC profit, what multiplier/chance do I need?"  Because available funds is a hard limit, and chance/multiplier isn't.  I'll look into changing it so that the bet size stays fixed when you edit profit.

Thanks.

dooglus - congrats on the successful launch and the size of the investments already made in the site.

I wonder if it would be possible to add a simple authenticated JSON API to allow me access to see my current investment balance, then I can integrate my just-coin holdings into other systems I use to monitor my bitcoins.

EDIT: never mind - I didn't see the other thread, where this has already been asked. Feel free to disregard.

Cheers,

Will
