I'm a regular viewer of a stream using deepbot and we have recently had to limit the betting options to a maximum of 50 "coins" (or points, or whatever you'd like to call them)
The reason for this is that there is no limit to the amount of options you can bet on and if the streamer died in the game, everyone watching got 5 coins. This meant that people could bet 5 coins that he would beat a boss and not lose any coins when he died. However at the same time they could bet the rest of their coins on him actually losing and since the game will kill you 90% of the time (it's dark souls 2, need I say more?) they were bound to win and get a profit regardless.
To limit this, the maximum bet has been restricted, and that is why it could effectively be called a bug. Is there a way to set a limit to the amount of options you can bet for at all or has it been thought about? If not, it's something that I personally think would be a brilliant addition to the betting part of deepbot and could help limit any exploits such as the one on this stream!
