I have IBKR and DEGIRO. As I approach 1M on IBKR I decided not to inject fresh money. The dividends from VWRD and VDEM (~ $10,000 per year) shall be changed to CHF and invested in CHSPI (also on IBKR) on a quarterly basis.
If I will deploy fresh money in 2025, it will go to DEGIRO and ACWI in CHF.
I will think about a Swiss broker in maybe 3-5 years, hoping that competition will bring about even better offers than today.
