I have a new question about the ability to play and to use the bitcoin for that. Can one play online casino games using the bitcoin currency ?
You can and it even better than playing for $ because you can play casino games without registering to the site and without downloading any software for playing, although not all sites gives this option but there a few sites that you can play there instantly and the withdraw of your wins (if there are any .. :-) ) are almost instant as well. you can try this bitcoin casino web site, which i personally like and played there a lot.
There are quite a few now, but a couple of things to keep in mind when betting with BTC.
DoubleDownBTC - Blackjack
Seals With Clubs - Poker
