In online gambling which you may call it "Virtual Gambling" , you are all alone siting in front of your system. If you are happy winning or sad/crying losing, no one will know it.
As if your family and friends will babysit you being a cry baby or being sad because you lose in gambling. Real friends and family won't allow your or spoiled you playing gambling, in fact, they are going to do the opposite, which is to oppose you in playing gambling, while fake friends will, and will only remain in your side if you are making profits or money in gambling, but if not, they are all invisible while you are murmuring in your room about your losses.
Virtual gambling gives you more of what you called "
Privacy", with that, you could focus even more and you could live your life peacefully, because no one would nag at you because you are playing gambling and no one will judge you, ain't that good for you?
