What ETFs have you bought and has it been a good investment for you? I want to invest but want to do it passively, so thinking of starting with just ETFs first?

If you're not sure which ETF to invest into, you can consider using roboadvisors as well. Platforms like Syfe and Stashaway are pretty simple to use, and provide a basket of ETFs for their investors, ranging from index ETFs to equity ETFs etc. Hope it helps!

My belief, but no guarantee, because I'm not an advisor:

particularly beginners but not only beginners are best advized to periodically (f.ex. quarterly or semi-annually) buy a broadly diversified (ideally global) stock index ETF and than have patience, patience, patience (... for at least 15 years).

Concrete examples could be

-for U.S. investors: VT (or U.S. stocks only: VT)

-for Singapore investors: ACWI/SPYY, SWRD (or U.S. stocks only: CSPX)

good luck.
