$14.5 billion

Biggest crypto theft ever. In 2020, a hacker cracked one of the world’s largest Bitcoin mining pools using a laughably weak 32-bit security system you could brute-force with a gaming PC. They drained 127,000 Bitcoins (worth $3.5B then, $14.5B now) from over 5,000 wallets and then just left the stash untouched for five years.
