At least it can reduce the number scammers who are increasingly right now, and most importantly the government must get
a large tax. But there are still many countries who consider it online gambling is an illegal activity, and it's very sad for me. But
fortunately there is a bitcointalk forum that can provide good reviews regarding online gambling.
Of course bitcointalk is a great help for all gamblers who seeks good attention towards promoting every community. About it's legality, well that depends on government concern because that's too controversial due to several factors. Many politicians will oppose to a gambling operation specially when it affects every individual. Virtualized gambling is a good alternative instead of physical one in order to minimize addiction, as it will be more optional compared to traditional betting.
