Many gambling sites have deposit bonuses.
However, if you receive the deposit bonus, there is a condition for withdrawal.
For example, 10 times the deposit amount, etc.
What is the reasonable condition you think?
LOL! What you are expecting? Gambling site is a business not a charity that's why you should expect for such condition into these kind of bonuses.
They wont give anything just for nothing where there would be always a corresponding terms which would lead out into their edge because wager requirements is
almost an impossible thing to beat.
