Is Stashaway safe? What is the minimum risk?

I think Stashaway is suitable for beginners and they have questionnaire for u to assess yr risk appetite to decide yr portfolio.
If u r really conservative person, u can start with a more conservative portfolio and adjust along the way when u gain more experience.

The risk involved depends on your risk appetite. You can adjust the risk you want to take on a specific portfolio. For StashAway, on a more conservative portfolio you can have a minimum of 6.5% downside risk and on a more aggressive portfolio you can have up to 36% downside risk based on personal experience.

Ultimately the algo helps you re-adjust your portfolios as well so its really a hands-off experience. The only level of experience i think one might need is the basic understanding of how robo-advisors work and the basics behind ETFs, so that you won't panic when there are short term losses/fluctuations in your portfolio.

In terms of "safe" i believe most if not all robos have separate custodian accounts where customers' funds are stored, so not much of a risk there. You can explore what others have to say about the different robo-advisors here: https://seedly.sg/reviews/robo-advisors
