One thing you should know is that bitcoin wasn't created by the government and they cannot regulate or control the price which gives them much reason not to support it. Anything that the government cannot use to benefit from the citizens through manipulation, they frown at it. Bitcoin gives them less power to control your financial life and the government wants to know about every penny that leaves and enter your account.

Bitcoin is not gambling and gambling is centralized, which makes it easy for some countries that banned it to reconsider lifting up the ban from gambling. They have cone to realize that it can be a source of revenue to the government.
