In the foreseeable future, each developed country will create its own crypto currency, provided by the national currency.
How much can this contradict the very idea of Bitcoin as a free, decentralized system?
Need cryptocurrency state control?
How?
Who has a million computers to run this network? Are miners going to get the money, if not why would I run a mine?
Are governments and central banks going to give up control of supply, distribution, and valuation? If they are not going to then why would I use their money instead of bitcoin?
The best a nation could do is to make a bitcoin-like alt-coin that only works in one country.
Who want's that?
