Online casinos often operate in a legal gray area, especially the ones that make use of Bitcoin. They might get ignored by the authorities because it’s legally questionable whether cryptocurrency is even money, but you shouldn’t count on that. Any gambling website can disappear without much warning because the authorities got a little too close to its owners.
It’s also tempting for the owner of an online Dice to disappear with the investors’ Bitcoin. Going by the comments on most BTC lending services, lenders are often leery of investing their coins to certain people because they may have been burned by borrowers who disappeared with their money a few times.
If you find a Bitcoin Dice game that looks attractive and you’re thinking about investing, listen to the guys who have actually played on that site. BTC users have learned to be leery of anything that looks shady, so they can steer you away from a service that makes it difficult to cash out or engages in any other shady behavior that might indicate that it’s going to disappear with money owned by investors and players. Some sites are pretty reputable, though, so you may find one that’s worth investing your cryptocoins in.
