A cost cutting campaign is usually a sign of declining business. I think the business is going bust and they're trying every method possible to save their last pennies by scamming users and removing bonuses and promotions. I think this is a warning before they completely go bust and vanish with our money.
In a way it's true because how were they able to keep the business afloat for so long when they're really not making that much profit due to their generous promotions right? If that was really the case they would've made something about it early on and they should've talked to their customers about it so they won't be surprised about it. If this is really the sign, I just hope that people that have been playing there or have their money stored hopefully can get out their money before it's too late for them, with the multiple scam accusations about them recently I would probably think twice letting my money stay there.
But I would also agree with the above poster. It seems like they are just readjusting as well as remodeling their promotions to fit their current goals.
Did they explicitly said that they are going change or that they've given their players some sort of early warning that there's going to be a change in their casino? Because if they did then it's in their right to do it and have the people just go with the new rules but if it's not then they fucked up because people are surprised about the changes and they weren't even probably considered or consulted about the changes.
