I just wanted to share a piece of advice that I learned early on from Andreas Antonopoulos (if you don't know whom this is, I highly recommend looking up his YouTube page and watching his videos and or reading his book Mastering Bitcoin) never tell anyone how much bitcoin you have. Andreas use to say it's not our job to teach everyone we know about bitcoin, letting them know we own some "Let that be my job" he would say.
Telling someone how much Bitcoin you have is obviously rude because it's the same as telling them how much money you have in your bank account. These people can cause a lot of problems for you because you never know who you will give your secret to. Alternatively, you might say that while the person is filming, he might share the video online and you have no idea how many thousands of people will watch it.
Since a smile is only on the face and we have no idea what is really going through people's minds, we should exercise caution when doing things or disclosing our secrets to others. It's as if you were disclosing your secret to the world and they might start looking for your investment in an attempt to con you.
