Would you say its been going on for some time now? Even back then I wonder why would ppl talk about it so freely etc.
I don't think this issue solely pertains to Bitcoin. Who would go on the streets and call out publicly that he or she owns a shit ton of jewelries or valuable watches? Or who would say that they have a bag of money in their basement? I think it is much more basic than saying that claiming to have Bitcoin is dangerous. I would just not brag about my wealth or specific possessions in general.
