This is the difference you missed when you say you don't see the difference between investing in stocks and gambling sites.
Most of the investors in gambling sites or casinos are really gamblers in real life, they know they have the disadvantage so they understand that siding the casinos will make them profitable. This thread is already telling us investing in a casino is profitable since this thread has been running for months already, and profit so far.
Better.
No middleman.
You go directly to a gambling site, input the amount you can risk then Voila! you have shares already.
I like this better since I can understand it plain and simple.
There might be more risk, but like they always say "the house always wins".
The risk factor is the trust issue. But with Yolodice, there is no problem with that.
All you need to look is the price volatility as you are almost guaranteed with a profit knowing a reputable casino would always win most of the time. It's actually an easy way of making money, the difficult part only is in the beginning and that is to search for a gambling site you can trust with your money.
