Well in the beginning we wanted to advertised Bitcoin itself, and personally, I have printed a Bitcoin logo in a shirt way back 2018 and I try to experiment with it going into the public like casinos if I would attract or someone will approach me and asked about it.
Some people still feel like doing this, but because they know the huge danger it poses, they avoid it and anything that would identify them as a crypto person. Where i come from, if you talk about having bitcoin, people think you are rich, they don't even know if what you hodl is less than $50 worth of bitcoin, they just imagine that you are an investor and you should have money. It is crucial to do everything possible not to attract attention to yourself as a 'crypto person', it can lead to a $5 wrench attack, and you'd lose everything.
Losing your privacy and putting yourself in danger does not only happen when you have a loud mouth, you must also be careful on how you reuse addresses, and if you want to spend bitcoin in your local store, common sense should tell you not to use the address that hodl's all your bitcoins.
