I think Bitcoin community must try to lure Fiat community ( 83 trillion $ value ) while the whole cryptocurruncy its with Total Market Cap: $159,648,842,543 not even 1% of the whole fiat community so i think not time for collision with Governments or Central Banks or the whole Fiat currency community i think we have to find a way to manage Fiat to Crypto gateways targeting mass adaption , that why i adore Ripple because of its initiative to infiltrate central banks .
