Digital money was not developed to be held as a national currency, read about Venezuela launching Petro in February 2018.
Idea is to be able to cross borders, hold a better value (not being central bank controlled), transact cheaper, be international where checks and balances are spread throughout the world to keep the blockchain information (miners) working throughout the world, safety and security became the next feature that is being investigated, worked on.
Relying solely on local fiat has become a nightmare with governments and bankers printing more paper money to try hold onto runaway hyperinflation, committing country into poverty.
Sorry I do not agree with you, moving forward into the 21 century financial instruments need to change, digital money on blockchain technology if done correctly should work worldwide within the next ten years. This is my opinion @cloudblade each to his own.
The state and the bank print the banknotes, but he does not have enough gold to guarantee. Those banknotes are in the eyes of everyone. He is only the government in the set of money. If it is a good government, it is naturally no problem, but when the government is weak, it does not provide Enough gold to guarantee, how to trust it?
The same reason...
The issuer of the crypto currency, almost no gold is provided as a collateral, but the risk is dispersed in the hands of the holder, relying on confidence, when the holder has confidence in this crypto currency, it can Use, when the holder has no confidence in this crypto currency, it becomes a waste coin...
However, at present, there are organizations that have advocated that the crypto currency they issue will provide valuable assets!
crypto currency has been used for shopping for more than a few years. The reason why it cannot be widely used is that its value lies in the confidence of the holder, so the fluctuation is too large, many businesses can not afford its fluctuation, so it is impossible to accept the secret currency. Payment to shop.
The crypto currency is at the mercy of the confidence of global holders.
The nationally printed banknotes are at the mercy of their own national strength.
When the national strength is strong, the secret currency is not applicable.
When the national strength is weak, the crypto currency is very applicable.
For example, the US dollar is more useful than the crypto currency, and the crypto currency is more useful than some currency of small countries.
Fiat currency (paper) and digital money (FinTech) both on a trust factor in value, supply/demand. No fiat currency is backed by gold!
