There is a series of TIME coin at Cauldron these days. I don't know whether it can be trusted, but I bought a bit each. Maybe it suddenly became expensive.

The Cauldron mechanism is still very prone to scams; adding liquidity and withdrawing it is too easy. There should be a lock-up mechanism, for example lock a year when created a coin.
