What are the betting limits?
Any bet from 0.01 is accepted.
I don't understand how you can run this without having a maximum bet size.
Let's say there are 6 million BTC in circulation, I own 5 million of them and decide to throw them all into Double Trouble... You can't pay me 10 million BTC if I win.
Crazy example I know, but you still should set a maximum.
e.g. If I bet 10,000 and win, can you afford to pay me the 20,000?
