Guess the smell of money in the thread is very strong and attracts some sharks. 
That's exactly what I thought when I read through the offers ... something along the lines of:"Just give me 1% of the money up front and I'll put you in direct contact with the CEO of BC.Game, I swear!!!"
But OP is certainly smart enough not to fall for such offers ... neither should anyone else reading this thread who may also have problems withdrawing their coins/credits from BC.Game - for whatever reason.
