Dev's should get USO listed on crex24,Hotbit or unnamed... 1st 2x will be more costly than Unnamed tho.
All have professionals running the show and great support.
https://www.unnamed.exchange/ is run by old guards of crypto and has multi trading pairs and could be a good starting point for USO on real exchange.
We don't plan to to the exchanges before we release the Android app (which is 50% ready) and GUI desktop wallet. First things first.
