Bitcoin has come a long way. It can only get better. As a matter of fact, the coin has endured various censorship campaigns bouncing back stronger.
But it has never warranted such attention from the government. I'm aware that they can't stop people from using it, but bouncing it into the grey area won't help at all.
And also the tracking is really improving, Bitcoin isn't anonymous after all...
bitcoin has never been anonymous so you can not say that it has changed because tracking was improved! in fact the focus of bitcoin has never been anonymity to begin with although it can provide you with enough anonymity that can sever your purposes as a regular user (meaning if you are not a big criminal). all the tracking techniques aren't reliable either. they only can come up with a good guess unless you have actually tightly linked your bitcoin addresses with your own identity.
