I saw this meme today, which sadly represents the way companies handles our personal data and our privacy.
I believe this image represent very well an answer to "I have nothing to hide, so I don't need privacy" argument.
Sadly even in bitcoin related companies like
ledger we have repetitive personal customers data leaks.
The best we can do is to follow privacy guidelines. I am often asked for my documents, addresses... I tried to dodge those requirements as often as possible, but we are all living in a picture like that when we talk about data privacy.
