To be honest, I'm tired and my opinion about cryptocurrency has changed over the past 7 years.
Now the source code of all components of the project is open (except for legacy, which will be closed).
As for the holders, they can either swap their USO to ETH through a
web wallet, or find someone to continue developing.
Sad to see old timers being tired and disappointed. I can only guess which way your opinion on cryptocurrency has shifted...
In fact cryptocurrency didn't change (except for quite a lot of technical development), but the user base has steadily degraded year by year, with the involvement of wider masses. IMHO. In any case this is inevitable. Cryptocurrency cannot change people by itself. People will modify its purpose and change it to fit their existing views and expectations.
