In some ways yes, in other ways no. Of course, the aim of the operators with the provision of a casino bonus is that you spend some time in the respective casino. Hence the wagering requirements. The online casino wants you to be able to try out and get to know the casino for as long as possible. The advantage for you is that you can extend your game. So you can continue to play even if your own deposit has already been used up. This of course increases your chances of turning a possibly losing game and taking profits from the casino. Ultimately, both parties benefit from a casino bonus.
