If the site was making a lot of profit and the owners were the same, I highly doubt they would cancel the signature campaign.
This industry is getting tougher. You need really deep pockets to survive and one small wrong decision can lead to massive damage. We have seen a few examples (I dont want to name) where very reputable casinos are withholding the payments for no reasons for months.
Sometimes short sighted projects use selective scamming in order to get out of the pit and almost all the time it does not work.
Not many casinos can really run for many years. Aside from running the platform, they also need to have funds to pay for their users or customers. If the expenses goes above than their income and they can't fix that issue then they might really stop operating.
The only bad thing with it is when this happens is those casinos, same with other projects is that they don't tell to their users this reality and hide it from them. Until people realize something wrong is happening then only the truth will be revealed. It would be better and understandable if they just revealed it in the beginning rather than become a scammer to the people that supported them.
Nobody would stay with the project if the truth would be revealed as soon as things get tough.. Unfortunately (or more so logically) - profit is a helm, not humane ways of ending ones path.
