If you live in a country using other currency than the casino, take care of the real bad exchange rates the Electronic purses use.
I can easy send Money free from my bankaccount to the purse, and it arrive instantly in SEK.
When I send to the casino, it is changed to Euro at a very bad exchange rate. The withdraws are changed back to a similar bad rate, and it cost a fee to get it to my bank account.
It is a very expensive way, and all near all costs are hidden.
So the best is to open an account in companies as Skrill or other in the right currency for example Euro, Sterling or Dollars. Then send the correct currency changed in your bank to avoid the bad exchange rate twice.
