If you wanted to compare two currencies and compare the level of decentralization, what measurement would you use?
Assuming you could know any information you needed about the number of miners, mining power distribution, number of users, etc.
I don't think we can see decentralization if you are going to use those parameters,
decentralization to me is free from a third party intrusion and government intervention, we all know the traditional way like Paypal and credit card payment you need to go through a a lot of verification and you only allow to use one account, with cryptocurrency it's very much different.
But as long as a small groups of individuals control it and charging for access to use it.. isn't it just as bad as the government controlling it?
