I registered this site a few days ago. Maybe about 5 days ago. But I did not receive 0.001btc to my account. After registration, I checked my wallet with only BTC 0.00000035 balance. So need I to do any works further like "claim" or "something" for getting the additional Bonus?
Have you made a bet before making a withdrawal?
I don't think they will give it away just making an account. It must have a condition, rollover or something like that in order to make a withdrawal.
