Sorry to burst your bubble(hehe), but it's really pretty much impossible for bitcoin to have no government regulations. Heck, I can almost guarantee it that more countries are going to ban bitcoin(probably temporarily) once they feel threatened enough by bitcoin. Probably a better and more realistic sort of "dream" would be for the governments to declare bitcoin as legal tender, and to implement sort of "fair" tax laws concerning bitcoin and cryptocurrencies. Yea taxes suck, but let's be real here. They're going to make money off the taxes as much as they can.
Legal tender is probably the best solution since this would mean that Bitcoin is just like other kinds of money, and it does not get heavily additionally taxed. As for the ban, I don't think it's likely. A lot of countries have pretty strong democracies, such a ban could lead to protests and anti-governmental feelings along with the growing popularity of Bitcoin would be too bad for such countries. Countries like North Korea can ban Bitcoin, but countries like the US or France cannot do that, because it is too risky for them.
1 . BTC will be the primary money all over the world all the currency will be just secondary
2. All the world currency will be exchange to bitcoin slowly until its all illiminated
3. Altcoins will be use for very country and bitcoin as its Superior
Unfortunately, Bitcoin is currently unable to be #1, the scalability issue is very serious...
