If as you said, you are not willing to use bitcoin in public, it means that you do not want people to know you are a bitcoin investor. If everyone is like you, how can bitcoin become a currency, a means of payment when everyone hides that they own bitcoin? We always want bitcoin to become more popular, always want people to know more about bitcoin, but meanwhile we are afraid to use bitcoin or spread bitcoin to others. How can bitcoin become popular?
And with that been said, I wouldn't have to blame the woman because she made her exchange physical and obvious and I also wouldn't expect the woman to ask her customers the source of their wealth before trading with them because I believe bitcoin is decentralized and as such she wasn't expected to ask her customers how their bitcoin is gotten because there are people who earn and own bitcoin genuinely and I think the security officers were to rash with their decisions.
I'm sorry to say but I dont see myself leaving bitcoin ever because everything I've owned is courtesy of bitcoin and I wouldn't say I'm extremely careful but I think I'm conscious enough not to let people know I own bitcoin and that doesn't mean I don't preach about it in the little way I could and I've also held seminars in my local church
to enlighten people about it but everything should be done consciously.
