Your bitcoin is your private asset, you don't need to show people your assets just to show off or make them see you differently, that's too dangerous because your endangering your life. It can as well be that he is showing his friends the profit he has made so far from his bitcoin investment out of excitement, without any intent to intimidate them, but human beings in their typical nature will always read meaning out of everything. This just goes out to tell us that, whatever we are doing that involves profit making, we should just mind who we share our certain personal information with.
Of course we don't need to publish how much we have accumulated in Bitcoin assets, even though we don't intend to show off what we have, it could be that the views of people who hear what we say are very different and this will likely be a problem when we show off our Bitcoin assets. we have collected this, as you said is very true, it could be that after we show off these assets it will endanger our lives because we will never know for sure who will try to control the assets we have, because currently most people have understand well that Bitcoin will be very valuable in the future even though they do not yet have a good understanding of Bitcoin.
you are right, when we talk about things that are very valuable in the future of course we have to be able to choose the right person to talk to us about and of course we can completely trust them and they will not betray us with what we have shared with them, because If we choose the wrong person, of course this will seriously endanger our own security.
