there are currently 2 devs for wdc.. Currently working on a huge wallet project for wdc
and there are other projects in the pipeline..
http://worldcoinforum.org/ for any information there are normally moderators or devs in the forum chat 99% of the time to answer any questions
Take a look at the forum and you'll see that alot of effort is being put into making wdc a successful coin, and not just another dump and leave coin
