I wouldn't worry too much about it at this point because if you think about it, the government probably has all the information needed to control and spy on you already, even before your introduction to cryptocurrency so no point worrying, they won't probably go rogue suddenly if you are living in a first world country.
That's a big assumption to make. First world governments frequently "go rogue" and ruin the lives of any citizens they decide are causing too much of a problem. The US government is undoubtedly spying on you constantly and collecting huge amounts of data about you, unless you are taking active steps to maintain your privacy. A very basic step in that process is not letting the government know exactly how much money you own and exactly when and where you spend it.
But why should they track my wallet?
Exactly. We live in a surveillance state, but they have no right to blanket monitor everyone's financial activities. If I'm not doing anything illegal, then why am I being monitored? Whatever happened to innocent until proven guilty?
The old cliché is often mocked though basically true: there’s no reason to worry about surveillance if you have nothing to hide. That mindset creates the incentive to be as compliant and inconspicuous as possible: those who think that way decide it’s in their best interests to provide authorities with as little reason as possible to care about them. That’s accomplished by never stepping out of line. Those willing to live their lives that way will be indifferent to the loss of privacy because they feel that they lose nothing from it. Above all else, that’s what a Surveillance State does: it breeds fear of doing anything out of the ordinary by creating a class of meek citizens who know they are being constantly watched.
