Europe expat, likely to move a lot. Where to invest when you don't know where you'll be in 3 years?

Hey everyone,

I recently moved from France to Denmark for work and I'm looking for advice on how to manage my investments. My situation is a bit particular and I'm lacking a clear strategy.

My situation

I'm 28, French, just started a new role as Project Manager in the data center construction sector in Denmark. I'll likely be moving around a lot over the next few years, whether it's within Europe, the US, the Middle East or Asia. Geographical mobility is a key factor in my investment choices and I don't want to lock myself into products that don't work once you cross a border

My salary is 4 000 € net per month. Housing is covered by the company so I have a solid savings capacity.

What I have

• 20 000 € available to invest
• No debt

My goal

I want to allocate around 2 500 € per month to investments going forward. I have my emergency fund covered, now I want to make the rest work for me. 100% passive investing, I'm thinking mostly about ETFs

My questions

1. IBKR, is it the obvious choice for someone mobile like me?

It seems like IBKR is the go-to for expats who move around. Is it really the best option for a passive ETF investor with no fixed base? Any alternatives worth considering?

2. Which ETF?

I'm looking at global ETFs like VWCE, VWRA or similar all-world funds. Is there a clear winner for a eurozone based investor? Should I care about USD vs EUR denominated funds given I might end up earning in different currencies?

3. How would you split my 2 500 €/month?

That's really my main question. Would you go all-in on a single all-world ETF via IBKR? Or would you diversify the approach depending on where you're based?

Thanks in advance for any advices you might have for me
