I'm sure the governments will find a way around the limitation of the number of coins in bitcoin if they really want it.
Final number of bitcoins is limited to 21 mlb coins, and if the govenments will decide to brake this rule, they will need to breake bitcoin protocol, wich was not possible possible so far. There are also estimations that 25% of bitcoins have been lost for good.
In my own opinion, even government will broke the rule, bitcoins will still continue to grow because people can always invest in the market if they are interested on cryptocurrency.
Bitcoin price will increase but 1 Million is the too much high amount which we don't have any clue. Of course, many people seeing how potential the Bitcoin is going to be but 1 Million too much high amount it will take nearly more than 10 years to reach that value.
