Someone was reported to have made his fortune from cryptocurrencies. His father was kidnapped. The kidnappers demanded for ransom but not stated if the ransom was bitcoin or any other cryptocurrencies. I tried to read other news but I did not get the details of the ransom asked for by the kidnappers.
You can read the news yourself from any of these two links:

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.
This isn't country (france) specific. People have known about the "wrench attack" for a long time. As the weakest link in uncrackable security of privatekey, is the person owning that key.
People have been kidnapped and robbed before in other countries as well because of their crypto holdings, that's why holders in the internet usually want to stay pseudonymous.
Because it's not the crypto they are really after, but the fact that people are flashing cash out in the open. Wearing expensive watches and using their real names and posting locations they are in. Those people will eventually get targeted if someone finds their weak spot. Publicly telling people about your relationships with different people is definitely one way in, as friends or family don't necessary have their own security.
