Can the same be done using USD to invest in VUSD instead of EUR or GBP for SRX8/CSP1?

Older posts in this thread recommend either EUR for SRX8 or GBP for CSP1 because it's not possible to transfer USD from Instarem to Trade Station Global? is this still the case? because the Trade Station Global page on opening an account states the requirement of minimum USD 1k (https://www.tradestation-international.com/global/open-an-account/)



and Instarem's landing page has selection to convert from MYR to USD.

Is this method feasible? or am I missing something.

Probably being naive, but I'm more inclined to invest in VUSD because it's more liquid and USD is easier to move around.

Another thing, this thread's recommendation to achieve the lowest fees for small time retail investors to DCA is to accumulate ~RM8k, then convert to GBP and wire transfer to Trade Station Global via Instarem, then purchase CSP1.

Or conver to EUR, then purchase SRX8.

Do these still hold true in currently?
