You can have a medium of value that is ruled by the users, not governments/banks and the rules of the game cannot be changed on you without consensus of the community as a majority (i.e. Fork). Even in crypto currency's that have inflation you can delegate who is the beneficiary of that inflation for the productive value they are adding to the society (Steem/EOS systems). So for the first time we can buy in to currencies that function by design that we agree with.
You can trade in your Fiat currency that is centrally controlled in the governments can just print the money in the beneficiaries of the inflation are the governments and the big banks .
The delta between the utility of those two types of currencies is value which has been reflected in price discovery in the past 10 years.
right but how is value created! If there is a feature u think is value u must explain how it generates value
