I think you got it right, we always thought that it was gambling all along, I mean gambling to make someone rich, but I think too now that it makes sense when someone is being rich by investing in some gambling sites or casinos. There are a lot of gamblers in these forum and I know they bet a lot, a lot enough to make some investors get back their investments.
I think bettors reading these will change their point of view with gambling and might switch from gambling to investing.
Investing in casino sites is always better then direct gambling as we all know that house always wins so if we invest in good reputed casino then we will be making enough profits on regular basis and chances of loosing money is also less if you invest in good site.
