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.
