Referral bonuses are just baits to win people over. In reality, its not what its actually presented as. The conditions are always vague until it gets to withdrawal, thats when you actually know whats at stake.

So they get gamblers in through those ref bonuses and promise them juicy offers and at the end of the day, you have to either commit funds or you are required to hit an almost impossible target to receive the ref bonuses in reality.
