A lot of people think that they are completely anonymous when they use Bitcoin, and this gives them a false sense of security. In our research, what we did is that we crawled social media, like there’s popular forum for Bitcoin users called Bitcointalk.org, and we crawled Twitter as well for Bitcoin addresses that users attributed to themselves. In some forums, people share their Bitcoin addressees along with their profile information. So, now you have the public profile information, which includes usernames, emails, age, gender, city.
