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".
that is a good thing in advancing btc, it's just that it takes a long time to leave usd or fiat. because basically to leave usd or fiat depends on the authority of the government.
