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?
if in the future developed countries are able to create crypto currencies themselves, this will certainly affect the existence of bitcoin, and allow bitcoin to weaken because of this.
but that can all happen if the new crypto currency has the criteria and multifunction like bitcoin, if not bitcoin cannot be defeated.
