Pros: Lax jurisdiction towards sports betting - I was able to create a pinnacle account.
Also, I sent an email to Austrian's tax department and I was told sports betting winnings were not taxed at all.
From the research I did I can tell you that in most countries dedicating yourself to sports betting is a grey area since it's not considered a job, so I ended up going to the country where I found sports betting was 'whiter' in a way.
AFAIK Canada was a pretty good country for sports bettors aswell(no taxes, pinnacle allowed etc) but you can't move to most countries as a sports bettor without a job.
I wish Pinnacle was allowed in Ireland or UK to be honest, I would've moved there but no pinny registration allowed and I prefer having my own account instead of an agents'.
Anyways, if you find information of any other good country within the EU hit me up since I will likely end up moving somewhere this year too (taxes for sports betting in my country are quite high )
edit: Since I saw some people mentioning Malta I want to say that I researched about Malta aswell and from the ppl I contacted living there it seemed like they didnt give a fck about taxing sports betting, but I contacted Malta's tax department and I was told you had to pay taxes from sports betting's winnings, so it's probably not a good idea to move there if you win big amounts.
