Online Betting Currencies
On this page you'll find a list of currencies that you can use to deposit at various online casinos, sportsbooks, bingo rooms and poker sites. Some currencies are fully supported and you can both deposit and bet/play in that currency, whilst others are only partially supported - where you can deposit in your native currency but not neccesarily bet in it, with wagers taking place in a second currency.
Either way, the ability to make the transaction into and out of (ie: deposit and withdraw) in your home currency means no currency exchange fees and no worrying about what rate is being offered.
The page is ordered alphabetically, but you can find a list of the most popular ones here: British Pounds, Euros, US Dollars, Australian Dollars, New Zealand Dollars, Canadian Dollars and South African Rand.
