You should absolutely assume that if you wear a bitcoin cap in the mall that you're risking being recognized as a bitcoiner. Expecting people to look away to maintain your privacy is obviously ridiculous. Expecting people to refrain from documenting it, is obviously a gamble you're taking. Sure you can appeal to people to be classy, as you put it, and not index your face from a "private" (*cough* clearly practically public event despite the technicalities) Your opsec is obviously your responsibility and if you want to make sure you're not photographed at a private/public event either - hide your face - don't be there The equivalent of the request in your note is like asking the fed to not debase the usd, like, sure that would be great I guess, but im not counting on it.
