My dilemma comes from investing in the [VUAA.UK](http://VUAA.UK) tracker, offered in my currency (usd) vs investing in the [SPYL.DE](http://SPYL.DE) tracker, offered in Euros.
My broker is XTB, which takes a 0.5% conversion fee between usd and euro.
I'm not an EU or US citizen, and I plan to invest long term 20+ years, with monthly contributions.
From my calculations, I'd probably come out on top investing in [SPYL.DE](http://SPYL.DE), despite the conversion fees, because of its lower TER.
The main factor that could affect my profits would be the Euro/usd exchange rate changing drastically in the future.
I'm a first time investor. Are there any gotchas or potential stumbling blocks I'm not aware of by investing in a Euro-listed ETF rather than a USD-listed ETF? I don't expect to ever live in an EU country or use Euros in the future.
