Investing with Cash Plus / MMF

I have invested in Cash Plus for about 6 months. Starting with $100 during moomoo's Kopi promotion.
Slowly adding 1-5k a month into $Fullerton SGD Cash Fund(SG9999005961.MF)$ for a total profit of SGD 642 to date.
$Fullerton SGD Cash Fund(SG9999005961.MF)$ is more liquid comparing to MAS treasury bills, with slightly higher risk. But to me the trade off is acceptable.

Just started with $CSOP USD Money Market Fund(SGXZ96797238.MF)$ when I used moomoo's currency exchange from SGD to USD.
