I do not think there will be governments in a country willing to replace their country's current legal currency with bitcoin.
it will be very inconvenient, besides bitcoin still not eligible to be made as the currency of daily payment.
No government indeed will accept that competition and so the earlier some of the posters on this forum forget about that illusion the better. Bitcoin was made to liberate all of us from financial freedom and not to be in competition with fiats all over the world or replace them so lets use it when we find the need and let fiats also serve their purpose.
