Also, if the government tells you to stop using bitcoin because it is illegal according to their view, would sell all the bitcoins you have because of their power or will you fight for your right?
That's why stay anonymous. I see members post their social profile, picture, phone number, website address and many more things that can lead to identify you easily. It's not just the government you need to do it for your own personal safety.
When you will be known to have Bitcoin in your procession, people will think you are reach no matter if you have even lass than 1 mBTC. If they identify you in real life then bad people will try to take advantage from it. Thing can end very bad.
