Every one has his own speculation about bitcoin every ideas matter. Guys what's yours.
There are governments today who does not really like cryptocurrency to grow in their area and that being said , bitcoins will not be fully accepted on the community so bitcoins as a prime currency will not happen.
There are without a doubt some governments that are not going to adopt cryptocurrencies until it is very late and unfortunately for their citizens it is very likely that this is going to happen when most of the world have already adopted cryptocurrencies and that means they will not get most of the benefits, this is why countries like Japan have adopted bitcoin because they want to obtain the benefits for themselves and their citizens.
