You only lose your whole balance if you are unlocking for a while. If you unlock after a few bets, you just lose a little amount.
If I unlock for a while, is it stated "cancel your bonus" or is it stated "cancel your whole balance"?
Why would anyone agree to cancel his whole balance? If you continue to play nothing worse than exactly this can happen!
Got you here, because even after for a while it is still stated
Cancel Bonus and not Cancel whole Balance!
