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".
It will not apply to everything and they just want to hype their project it's better to post the link here so we can read everything about it, it's hard to leave your fiat for Bitcoin they can co-exist but never replace one another I doubt if there is a human alive that can live on bitcoin transactions alone.
