The only way to increase the bitcoin's value is to maximize its' usage if any government won't allow to use it on the state level.
It is not as much about government to let Bitcoin be used to pay taxes with it. We need more general adoption of big business.
Amazon, Apple, Google all kinds of technology giants - if they will accept bitcoin then the price will reach the moon.
Additionally - we all can influence Bitcoin price, even a little by spreading the words about it, tell your friends and family!
The more people know about Bitcoin the more will buy it and increased demand = higher price due to the limited supply of coins.
