I do not know from what you conclude that I think I am free
I wasn't referring to you personally; rather I was just speaking in generalities.
It is quite clear to me that we live in a totally spy society, all social networks, computers, mobile phones, cameras on the streets and shops are networked and monitor every person
Agreed. The only thing more worrying than how much corporations like Google and Facebook spy on your every move, photo, word, call, search, payment, etc., is just how little the general public seem to care that they don't have a shred of privacy left in their lives.
Thankfully, as time goes on, we are developing more and more ways to maintain and protect our privacy with bitcoin, and more and more people seem to be using them. DEXs are seeing more volume than ever before, and it was reported last week that they had more volume last week than in the entirety of last year. Mixers are more popular than ever, and things like CoinJoin and PayJoin continue to be developed.
