It's legal one.If the law is not stated anything about this, I am sure it was not a illegal one.Many people attract to gambling due to they will get real money as a winning price. If any gambler had worn atleast 1000$ in a single shot, they will addicted to play gambling at any cost.
Yeah, as long as the law does not give any restriction to gambling, then either in paper currency, or digital currency, there is no reason to consider it illegal, unless otherwise. Also, I really feel one of the bad sides some people have decided to impose on themselves, as gambling even got easier with bitcoin and cryptocurrency is the idea of making money gambling. I hope this won't start giving birth to more addicted gamblers.
a local exchange site prohibiting gambling funds from goig through doesn't really make it illegal. And if gambling online with regular money is very much allowed in most places, i don't think btc gambling will have a different acceptance. Its basically the same with.
The legality at the end all balls down to the gamblers place of residence. If it is illegal in their state, then it is illegal, either fiat or btc. The only difference that comes with bitcoin is that even if it is illegal, you can always stay anonymous, and cash out whenever you want without it being traced to gambling, unless of course, bitcoin or exchanges are now banned in such places.
