Crypto owners that are known to the public are getting targeted in France. You can remember the co-founder of French crypto-wallet firm Ledger, David Balland, was also kidnapped with his wife in January from their home in the region of Cher of central France.
You're not just attacked because you own crypto; anyone can own crypto and yet not attacked. You're going to face attack when you let the public gain knowledge that you own a certain worth of crypto. Say for instance the only crypto you're holding is worth just $100. Will that attract kidnappers to you let alone your family members? What if you hold $200k in cryptocurrency? And you didn't let anyone know that you good such amount of crypto, no one will be disposed to such information let alone try to device means of stealing your asset from you.
In summary, it's not just that you own crypto, it's what you do as a crypto holder. If you live a low profile life, regardless of the amount of crypto you hold, you won't endanger your life or that of your loved ones. Same with doing any other business and exposing how much you own to the public. no knew comes against what they know nothing about.
