Bitcoin was a prototype to what the future might hold but falls short of addressing centralized concerns and the powers that be can control all major stakes in a coin through POW or POS. Why is there no outrage over huge mining organizations? it's no different than a central bank that can inflate or deflate currencies with very little effort. The future looks bright but much imagination and work is ahead. First regulatory bodies will have to be eliminated coupled with a fair distribution system where hording huge sums of said currency is useless or even harmful to the horder.
Let us not forget, currency being exchanged for goods and service has value & currency sitting still serves only the ego of the holder at the expence of all others.
