This may seem like somewhat of a dumb question. When playing in online casino progressive games though if you win and are playing in Euros you'll get the corresponding amount paid out in Euros right. Like players that play in Euros get paid out in Euros, players who play in USD win USD amount for the progressive, etc...

I think it would make the most sense if the winnings were in the currency that you're playing in.

Can someone please confirm whether this is true or not?

Thanks

If you're playing at a casino that supports multiple currencies and you're playing in Euros then if you win the progressive you should be paid out in Euros. This is how it typically works with Microgaming casinos.
