You are talking shit about gold - it is used as wealth storage against inflation because there is limited amount of gold available.
Same is with bitcoin or any other limited supply coins - they will be used only for speculation or storage.
Bitcoin will never be used for payments so it could not be used for real economy.
Economy needs working fiat / assets / currency used for payment and you need to control it by emitting new coins or burning useless one.
As soon as there not enough bitcoins and last one would be mined, there will no possibility to make transactions using bitcoins.
Wrong, wrong, wrong.
Gold is not used by everyone because it is inconvenient. It is impossible to pay 2.99$ for beer using gold bar. 90% people that you will ask on the street what is "inflations" and how high inflation is now and why will not know the answer. Don't tell me that they people love fiats because government and banisters can still money from them. Its stupid. They are using it because it is a official way of payments, and they are too focused on earning and spending it that they don't spend time on educating how money work and why they are doomed to work till death because of banksters greed.
