Again, what can governments do? This is not merely an issue for individuals to consider. It's a society-wide problem, too.
Before the state acts, we should first evaluate ourselves, do they often show off their Bitcoin or other asset ownership? because it must be remembered that all of that is like Newton Third Law there is something that triggers it. Therefore the anonymity of bitcoin asset ownership is the main principle and is not immediately echoed if it has no benefits.
Thank you for your response. Beyond acting individually - an important facet here, though one that has been harped on more than any other - governments need to take security threats very seriously. Obviously, it's the nature of Bitcoin to attract individualists who believe in personal sovereignty, but this is slightly disingenuous as Bitcoin is becoming a reserve asset for nations and is being integrated into the core financial structure of the world. Thus, it's more than just an individual "don't tell people you own Bitcoin" issue. Governments must figure out ways to fight this type of violent crime.
It's both an individual and a society-wide problem. My guess is that this will make people think twice about establishing crypto businesses in France. This will hurt France.
