but there is no working stats, i was not lucky enought to hit the block, so i am not sure if it's as it sould be
Hard question to answer. it depends on how many in the pool, how many shares you end up with, how many blocks are found. There's a lot of determining factors. At the rate BTB's are being created, most likely quite a bit under 1 a day.
But the price of BTB's is comparable to the price of BTC's with people currently getting between 0.5 -> 1 BTC for each whole BTB so it would likely be quite profitable when compared to some of the other mining opportunities.
