I have purchased my first BTC on a regulated exchange with KYC. I don't prefer it because of privacy reasons, but I had no other choice at the time. From there it will go to my coldstorage device, which I consider reporting as stolen if a ownership tax is launched. However, authorities would know the BTC address (exchange will provide it) and every future transaction that came from it. So I could never move the funds after reporting it as stolen (I guess) as this demonstrates they were not stolen.
Can I transfer the BTC from my current address, to an address that no government can ever link to me?
there are still several mixer platforms operating so you can disguise your tracks from the government through them, that's also what makes me not really like what the government is doing with bitcoin, they just want to get tax money but don't want to be responsible when someone loses bitcoin from their wallet. The government has never found the best solution to deal with the difficulties faced by society, all they know is how to get more tax money quickly, while Bitcoin is here to be the best solution for the general public and to be a good and trusted investment asset, if more and more people lose their trust in the government then it is not the citizens' fault but it is all purely because the current government cannot be trusted by the citizens.
