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".
You should put up a link to a vital news or story you share here to authenticate your source. Otherwise, you are mere blabbing or playing to the gallery. On a more serious note, there's no way anyone can make fiat totally disappear in replacement for Bitcoin. That isn't going to happen. At least not in this century where a lot of countries don't even have electricity and Internet stabilized. The third world countries of Africa are glaring examples of "how not to make fiat disappear."
