I was following a thread and was amused by some of the answers. I'm interested to see how much people know.
Yes. It is possible to find out that you own bitcoin, you can not hide it forever. There are people who are curious about bitcoin so they will find a way to know more about this. They will know if you have bitcoin if you share your thoughts or information of it in social media just like in facebook, twitter or on youtube, and they will notice that you are engage of cryptocurrency when you shared some project on your social media. More over, if they will check your phone you have a different cryptowallet installed on your phone.And as long as you will not tell them how much you earn or how much you had on your wallet they will never know it.
