I'm open to the idea of transitioning a new dev to take over.

I would work on an android or ios app but the stores are strict and I would be banned messing around with btc/cryptocurrency(not worth the risk)(once your app is banned you lose all your users and it's hard to get them back). This is what would turn this project around and get the userbase that it needs to get off the ground in my opinion.

I left because it's a lot of work and the user base growth curve was dwindling and I have a cutoff point if a project is not showing enough growth. I would need some good ideas, additional devs and a winning revival plan to come back.
