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?
That is insane, I know sites who will ask you for a number of rolls before you can claim your bonus deposits but remember its a business. They will do everything to attract everyone to try their site and the same thing, they will do everything to keep you from playing in their site, just like the topic on the other thread, they will go to the distance to keep you playing, the longer you stay in their site, the better for their business.
