My vision for the site was as a community of small investors together building a decent sized bankroll for themselves and others to play against.  Not as a money-making scheme for a small number of already-rich bitcoin millionaires.

It may be "bad for business" to confront the gambler with an accurate statement of their position, but it seems like the decent thing to do.

I'd rather the player know the truth about their losses rather than lie to themselves that they are "about even".  Then they can make an informed decision about whether to keep playing or not.

The tricks used by casinos to keep players playing seem shady to me.  I'd rather give them the facts and let them make up their own mind.
