It is ok, because... use case.
For example, before listnerds was a thing, the only use case for CTP was HODLing for upvoting. Now you can use it for listnerds.
The team is active and constantly coming up with new projects, so CTP's use case will probably continue increasing.
As far as listnerds goes... building a mailing list is a slow and steady, constant labor of love. And there are so many different ways for the project to grow. I look forward when I will be able to use listnerds as I do mailerlite. I would be happy to pay fiat for the service, and even happier to use and burn my listnerds.
Its about vision. You have to have it.
But it is ok if you don't because there are a plethora of other projects to invest your time and money into.
