Just started using this site for my daily gambling and so far loving it. Is the active users count on top of the page really accurate? It can't be that so few people are playing and they are able to sustain the site with that...
If you are interested in how site is doing you can find more info on their Medium blog
https://medium.com/@BitDice last quarter they incured net losses of 74k, mostly on staff and legal expenditures.
They used to have more players and turnover before they organized ICO.
They are regularly slow at implementing anything users request or what they announce is never released on time.
Probably you shouldn't have problems with deposit/withdraw otherwise you must be very patient.
