I read the local news, and there is several articles that made me interesting, a few weeks ago, the mobile version of the Bitcoin wallet bitcoin platform decided to eliminate the conversion of bitcoin currencies with USD. then replaced with Satoshi.
the decision was taken to eliminate dependence on fiat currency. because bitcoin capability if converted to fiat, will interfere.
developer samourai wallet says "farewall fiat" or "goodbye fiat".
I think this wont going to happen. Fiat and USD are still powerful than bitcoin. They are more acceptable by all people unlike bitcoin that there are still some people who are against on it. It can easily replaced fiat and USD because it was supported by the law and the government. Maybe bitcoin has more high value than the two but that doesn't mean it bitcoin is now the no. Currency in the world.
