If I live in a foreign country (neither USA nor Europe) and I invest in a USD denominated ETF that holds European stocks and intend to hold it for at least 30 years, how does currency affect me exactly?
If the USD was to decline consistently over the span of my 30 year investment against my country's currency (which has been the case since forever) and also against the Euro, how would that affect me if I plan to sell my position in 30 years?
