Blockchain investigator ZachXBT clarified that he has not labeled the crypto wallet project Vultisig as a "scam." Instead, he criticized the founders for negligence and ethical shortcomings. These include refusing to refund fees incurred from illegal activities, employing North Korean IT personnel, and a personal wallet theft incident linked to a Telegram call hack by North Korean hackers. ZachXBT suggested that in the event of a serious future incident, he might avoid full responsibility.
