I'll try to played in bustadice sites and I win half of my capital, then later on all of my amount will lose. After that I've realized that all players with greedy thinking was not win up to the last. Playing in bustadice sites is very simple, I suggest to put some other features in the sites. Because not all people or not all players are wants to played dice roll, some of them are enjoying spots betting, POKER and other games.
But in terms of dice roll, no question that bustadice is the improved game of HI-LO.
Actually long run will always end badly, every players already know that, you should adjust some of your bankroll or your profit to stop. Btw I do not think they are going to have like what you said, adding some sportbook? This is not their things because from the start they are having the domain as dice game so it just impossible to have this kind of game added on their site
