The draw of gambling causes people to do things spontaneously. Just think of the $10,000+ bets that people have placed in RSGP. Not only do you have to trust the user with that money, you also face much steeper odds, yet people do it anyway.
RSGP is a virtual currency [even though it has a monetary value] - I think that is a lot different from an actual currency that can be converted to USD, EUR, etc. I may be wrong though. I saw the ups and downs of the RS gambling as well, it's immense. I know.
Whoever keeps saying the site is illegal doesn't know the gospel of Bitcoin.
I won't lie, I wouldn't know, as I don't use BTC. However, seeing BTC is considered a currently, I look at this whole thing as it were USD. And if you look at it from that prospect, these statistics, claims and numbers are extremely steep. Care to elaborate how it's not illegal though? I honestly don't understand [read what I wrote above, as to why I believe it is illegal].
Tbh, I am not siding with anyone here but I do work in a Casino... I do realize that what you are saying kfjjj seems unlikely for someone to bet and hold that much revenue in such a company, but what if this guy is a multimillionaire just having some online gambling fun? who are we to argue with who this guy is or what his past is or how much he is willing to lose. I use to think the same way before I go a job working for a casino where I now watch the same people come in daily and lose up to or more then a million dollars in 1 hour... It's insane.
You know, I'm 20 now - I've been gambling online since 13 and live since I turned 17. I have seen nearly everything up to this point and it's just beyond me why someone [in your scenario] who is a millionaire or just simply rich would want to use such a simple site, when there are gambling sites which strive to make your gambling experience a lot more addictive, which are also certified, licensed and offer a greater variety of ways you can lose your money

I've seen magical things happen in the casino myself, I know how it is

If all those numbers on PrimeDice are true, it's just beyond me, really.
I believe he only pays tax once he has sold the btc profit to buyers.
*EDIT - Also if you have ever sent/received btc you would know most people wouldnt leave their btc on the site overnight, you can transfer to an offline wallet instantly only costs around $0.06 per transaction and especially if someone profitted I doubt they would keep their winnings on the site instead of transferring to an online/offline wallet.
I wouldn't really know, as I have never dealt with BTC, nor am I planning to, to be honest with ya.
PS: Don't get me wrong guys, I'm not trying to thrash this website or anything - I haven't had any experience with them; I'm just curious as to what other people think and whether I'm the only one who is so skeptical about these things.
