Money leagues for European residents?

[theswede]

I'm from Sweden and would like to compete for cash prizes. However it is clearly stated the one must live in the States (and not even all of them) to enter money leagues - at least at the sites that I have visited. So my question is: How do Europeans (and US residents of the remaining states) enter leagues of this sort? Is there perhaps a (serious) site that accept us?

I'm terribly sorry if this topic has been posted before, but I really did try to find it.

Thanks!
