Want to truly diversify investments: $20-30k annually into EU market.

USA taxpayer here. Feel not easy with this volatility and US printing money.

Started already with NVO, like 4K since its crashed. Planning to continue buying shares of big European companies such as Airbus, siemens, apd rino tinto asml etc

1. Should I invest in local currency? For example euro vs GBP Vs USD ?

2. Which countries have a less tax burden for american taxpayers?

3. Any other thoughts ?
