The longterm inflation rate is the only thing that matters.
You seriously think YAC will be around in 30 years when the inflation is on par with that of POS? I do miss the APPLE ][ I played with in mid 1980s.
So you want POW coin generation rate to equal POS coin generation rate? Is that your new theory you just came up with? And 30 years really? Please educate yourself, become somewhat successful, obtain capital, and then come back, then maybe we can have an intelligent conversation.
And to answer your question if I believe YAC will be around in another 30 years... yes I do. I really do.
