In 1990s the USD was the only currency offered by online casinos. The USD was the mostly used international currency. It was a difficult process that required a lot of time, the players had to convert their money into US dollars in order to make deposits and to withdraw the cash.
After that the online gaming software providers made a change regarding the currencies online casinos, and online casinos began to accept the currencies of the players. The currencies were converted at the prevailing exchange rate. But anyway the players lost value at every convertion because of commissions charged by the banks.
So that the leading online gaming software providers as Cryptologic, MicroGaming came out with the real multiple currencies online casinos and nowadays the players can deposit, make payments, bank and wager in currencies of their choice from a list offered by online casino software providers. MicroGaming, Cryptologic and Playtech online casinos offer multiple currencies like USD, CAD, EUR and GBP. The online casinos require players to select the currency when they register. The players cannot change the currency they selected on their own. It is just one possibility to change the currency, it can do the casino customer support. The online casino will require from the player to fulfil his/her wagering requirements in the existing currency and withdraws the balance so that a fresh start can be made with the new currency.
Unlike a land casino, many online casinos accept multiple currencies so that two or more persons are able to play the same game using their own currencies. A person living in German can purchase credit in Euro while a person living in the United States can purchase credit in USD. This removes the inconvenience and confusion of having to firstly convert an unfamiliar currency to one’s own currency before placing each bet.
