Is DAI safe to hold?

I'm curious about DAI and its safety as a cryptocurrency investment. Could you please elaborate on the security measures surrounding DAI and whether it's considered a safe asset to hold? I've heard about its stability mechanism and collateralized debt positions, but I'd like to know more about how these factors contribute to its safety. Also, could you discuss any potential risks or vulnerabilities associated with DAI that investors should be aware of? Thank you for your insights!
