CoinEx News: Marathon Digital (MARA), one of the largest listed Bitcoin miners, disclosed in its latest proxy filing $869,160 spent armoring vehicles for its CEO and CFO, part of yearly personal-security bills of $4.3 million and $3.9 million. The filing is the clearest sign of a wider move: Bitcoin OGs are converting paper gains into armored cars and underground bunkers from operators like Survival Condo and Vivos. The driver is the "wrench attack" — robbers who physically force a holder to hand over wallet keys, because crypto moves instantly and irreversibly once credentials are surrendered.
