Well someone could be up 10 Audi's at this point. Do we know for sure if the big winners might also have put the site profit up high also at some point so as to have won back a lot of their own money.
This specific player under different names has been a new winnter of about 10000+ BTC, he has very deep pockets and an extraordinary amount of luck. He is not currently an investor (though used to be). Most of the profits or the site (which are mostly gone) have come from "smaller" gamblers - there are very few whales of this magnitude on Just-Dice or any gambling site. Who bets 50,000 USD per roll?
"Of course, there’s plenty of ultra high-limit baccarat to be found too. In Macau’s many VIP rooms, there’s baccarat, baccarat, and more baccarat. Many of them feature only baccarat tables, and even when other games are offered, they’re almost an afterthought. Alot of these rooms have limits of more than 1 million HKD per hand ($128k usd) and you’ll often be able to pop in, have a look around and see just why Macau is the world’s highest earning gambling destination.[1]"

No you are quite right. What is amazing is the low cost to start a high limit btc site vs that of building and running massive VIP casinos.
