Please share which casino accepts Bitcoins?
There are many trusted and old casinos that are using bitcoin as a bet. But why not try new cainos like I am promoting the AdmiralSpot. Here, there are many various game so you would not be bored. Yet, there are promos here like if you deposit 0.5 bitcoin you could play with 1 bitcoin.
There is no special thing with by deposit 0.5 btc you could play with 1 btc (if you ever tried on other site, this is called "deposit bonus"). When people already feel "comfort" with some old gambling site, they won't move to a new gambling site unless they are having a lot/big promotion and unique games.
