The more we talk about bitcoin, the more likely that people are going to ask how many bitcoin we have, and surely we can have friends and relatives who will ask and if we don't give them some reasonable answer then they are going to just make up shit or they might even tell other people wrong information based on their theories about how many bitcoin that you may or may not have.
This is absolutely true but since we don't owe anyone any explanation or detail of our Bitcoin investment so we should never in any reason tell people how much Bitcoin we have in our portfolio especially people that are not to be trusted and I think by all means we should try or learn how to bypass situation or event that will lead to disclosing vital information concerning our investment. And I believe this is the best way because no one will be sure or certain that one have some certain number of Bitcoin in his portfolio but if we encounter them one on one like you said there are respond one will give that can make them know you want to fool them and they will know you have a good portfolio and once that is known by people one becomes a center of attraction.
