It’s not a big amount but what should I do with $800? Keep in my bank or invest in a robo-advisor? If robo-advisor, which would you recommend and what portfolio?

If you're young, risk Taker, can consider equity100 from SYFE.

If it's spare cash, feel free to park in robos. If you can stay invested for long-term, feel free to adjust to a higher-risk portfolio.

If you need the money soon (number of months of a few years), consider stuff like Singlife.

If you need the money next week, then just leave it in the bank.

Have you set aside some emergency funds in case you need to use? If no then keep this as the emergency funds, if yes then consider syfe equity 100

Is this $800 spare cash which you wont need for short term needs?

if yes put in syfe equity100

if u are just parking it somewhere and wants to take it out in a few months, put in singlife or syfe cash+

I will recommend keeping in High-interest savings account such as SingLife if you are not a risk-taker and that you will need to use 800 in a short-med term.

Otherwise, you can put this into Syfe Equity100
