If I myself think this is a natural thing, we are all people here who admire Bitcoin, I think this is normal who then considers Bitcoin to have high potential. 
Whether it's in matters of legal tender or a very high value later.
But what I never agree with is when someone says that Bitcoin will completely replace fiat money, I totally disagree with this. Because at any time this Fiat will not be completely replaced by this Digital currency. But between fiat and Bitcoin, will go together according to their respective functions.
