That's definitely something I don't like to hear.

Why did you decide to sell your coins? As far as I recall you missed the lauch but bought significant ammounts later on. I understand that people can be anoying, but that'd be no reason for me to be not invested yourself. Maybe I'm overvaluing YACs features, but I still see them far better than some altcoins with a far higher marketcap. A nicer GUI, some minor fixes and Yac is good to go, or am I missing something important here?

Nevertheless loosing the main developer (again) will be a big hit to it.
