You can gauge your risk accordingly by reducing exposure in amount and/or time to make the these risks low/negligible.

But strictly speaking it will always be custodial and there is no guarantee that those who hold ecash tokens will ever be able to redeem them for real Bitcoin, or that others will take them at their represented value.

I think there will be many rugs by mints (both intentional and unintentional) before it gets somewhat better. But the risks will never be lower than self-custody on chain.
