Sorry to hijack the forum. Once again, thank you everyone here for providing valuable advice and information for us

Just wanted to ask everyone's opinion here. If you want to invest in S&P500, say hypothetically about 6 figures in cash for the long term, say more than 5 years, what would be the best option?

I'm thinking of Ramjade's method of opening a IBKR account via a CIMB SG bank and parking there? Or would it be more advisable to do it via Rakuten or any other local institution due to ease of legality, withdrawal issues etc?

Likewise what would be the best for a similar amount for US TBills Money Market fund?

Would appreciate advice. Thanks again
