Your safest bet is to swap your ESP for Wispr. You have nothing to lose, there are no buyers and this coin is slowly dying.
https://twitter.com/notsofast is now also shilling Wispr, which means that ESP is done for. Although I am still pissed how CC mislead the ESP community, there were some nice people among the ESP community, including Gandalf and Monoxide. I hope you guys can get a spot on the Wispr team.
There is a point where you just have to let go and move on to better projects. I am pretty sure that CC will soon stop working on this project and move on to new projects as well. It is what it is.
Agree with you, but I want to point one fact that you are wrong. The coins can't be lost if you send them to the right address, they are registered on the blockchain, the only issue is that the wallet doesn't show them up and this can be fixed somehow.
