It's a perfectly viable business model, just not something with guaranteed short-term results.
Thanks Rannasha for taking all these questions while I was sleeping. I love how investors feel - uh - invested - and so take responsibility for helping out newcomers. It's this feeling of community that I was hoping for when I made the site the way I did, with on-site chat and shared bankroll.
As for amounts wagered and invested, I occasionally update
https://just-dice.com/wagered.txt with the amount wagered each day (UTC), and
http://blockchain.info/charts/balance?address=14o7zMMUJkG6De24r3JkJ6USgChq7iWF86 pretty closely tracks the amount invested over time (it's the cold wallet balance, which doesn't include the amount I keep online to process day to day withdrawals, and does include player balances, which pretty much cancel each other out).
wagered.txt was just updated, btw.
The throttle limiters have done something to the socket interface. Bots are malfunctioning and the whole connection jams up when trying to use one that worked with Chrome flawlessly prior to yesterday.
It's not the throttling that broke the bots, it's the message that says "your bet is being delayed because you only bet X BTC". Previously, when a message was received, it always came when the bet was finished, and so bots were coded to send their next bet whenever they saw a message. This "your bet is delayed" message necessarily has to come before the bet has finished, so people can understand why the site seems slow.
If the bots wait for a 'result' message, they'll be fine. Or if they just ignore the 'jdmsg' messages, that'll work too.
