Any comment from the site owners about this?
After talking to 1 staff member (M.F., full name and private info known) [...]. If I ask what would happen if someone would win 100 x 20 btc (and investments would all be negative) he just said : "we will not pay him the won amount".
While I understand the short term benefits of refusing to pay out big winners it does seem a little shortsighted.
Is this official DaDice policy?
If I was looking for a dice site to play on, I might not chose the one which has a stated policy of not paying out people who win too much.
