Their safety shouldn't be in their minds all ppl deserve to be safe. It doesn't matter which job they're doing they've got a right to be safe. If they're visible like social media influencers or company owners they shouldn't be scared they'll be kidnapped or their families are in danger.
They must be worried about their safety and security regardless of whether they have a lot of bitcoins or not. Their faces and identities are exposed through videos posted on various social media - so many people must know them and bad guys will target them for easy money. You can't say they don't care - in fact, many influencers who have a lot of assets will hire bodyguards for their safety and their family.
As I understand it, attackers are not interested in celebrities, businesspeople, and politicians who keep their money in bank accounts, since they apparently do not have any information that these individuals have anything to do with cryptocurrencies. The attacks are clearly coordinated and designed to demand a ransom in cryptocurrency. So there is only one solution: do not talk about cryptocurrencies to anyone, and then life will be calmer. If a person does not have the opportunity to maintain their confidentiality, such as Michael Saylor, then such people will most likely have to hire a bodyguard.
