Really like the originality behind this idea.  I think it is a good idea in theory and might work if the site could attract the exact same player population as normal dice sites.  However IMHO, the negative house edge will eventually attract a whale with a large enough bankroll that will beat the house.  The type of whale that would not normally be interested in -EV bets.

Brings up a good point though that a site with 0% house edge could be profitable (could also possibly use ad revenue or another revenue stream that players would accept due to the 0% edge).
