Very sorry for your loss, dev. Hope you get through it well, I've been through the same a few years ago, just stay strong.
The dev has handed over the project to the community. I have the credentials for the github and the forums. I have personally paid for the website to be under professional development, using the recommendations given by the community. Continue to mine, continue to stay strong. Once we have a good foundation, we can try to get on an exchange. Without a good foundation, going on an exchange will be a waste.
Let me know if you need the design elements, I have the logo, font and color schemes prepared.
