I even know few guys who bragged many times in public on twitter how they earned moeny from crypto and they reported all the stuff they purchased including smartphones and cars, from Bitcoin profits.
How hard do you think it would be for someone to connect few dots and find their addresses and their real identities?
I guess not much for someone who is really interested to find this out.
I believe Jameson Lopp was also a victim of a targetted attack because of his Bitcoin.
Yeah he was one of the victims, and that is why he is trying to help other people and keeps updating
list of all known Bitcoin attacks on his github and website,
There is no better man to listen if you want to protect yourself from attacks like this.
