Is there a coin that rewards newsletter subscribers?

I run a small newsletter about building great products and have been thinking for quite some time about a way to monetize that rewards Early subscribers.

I’ve been thinking about creating a cryptocurrency whose economics reward holding or buying in early (e.g. fixed supply).

I’m not a crypto expert so I’d prefer to use a service that thinks through the token dynamics for me so I don’t make stupid decisions.

Any chance something like this exists today? I think my subscribers would dig it.
