The first thing that came to my mind after reading this was that one should not talk about his crypto investments with strangers or friends as it can pose various risks. If you are active on forums like bitcointalk and involved in trades, you should not give information which can help others relate to your identity.
It may be an exaggeration to describe our investment and financial lives as “secrets” because in many cases there is no harm in sharing them with those we trust, but it is important to acknowledge that excessive chatter can attract hunters who will seek to get part, if not all, of your profit pie in anyway or another. And here I do not exclude extortion or the threat of harm if your interlocutor knows that you are keeping a secret that can cause you trouble, especially for those who live in countries whose legal legislation does not support crypto. This also applies not only to investments in Bitcoin, but to all types of investments in general.
