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?
Although many countries will creating their own cryptocurrency, i believe when they want to trade with other cryptocurrency, they will need
to convert their crypto to bitcoin first. Bitcoin is a global and international cryptocurrency, everyone can use it unlike national currency (their own crypto). So, it won't contradict if there are many countries creating their coin.
