Thread (6/10) 🧵 The 2013 Warning Signs March 2013: A transaction log bug caused a 23% crash in BTC price. April 2013: Mt. Gox suspended trading—causing a 50% crash. May 2013: A $75M lawsuit + U.S. Department of Homeland Security (DHS) warrant led to seized bank accounts. June 2013: Mt. Gox suspended withdrawals customers couldn’t move their BTC. At this point, panic was setting in. But most people still believed Mt. Gox could recover. They had no idea the Bitcoin was already long gone.

Thread (5/10)🧵 The Silent Theft: 2011–2013 In late 2011, hackers stole Mt. Gox’s private keys—due to an unencrypted wallet.dat file. From September 2011 to 2013, the hacker slowly siphoned BTC from Mt. Gox’s hot wallets. By mid-2013, over 630,000 BTC had been drained but Mt. Gox didn’t even realize it because they were still processing withdrawals with new customer deposits. The exchange was now operating like a fractional reserve bank with no clue that their funds were already gone.

Thread (4/10)🧵 The First Major Hack in 2011 June 2011: Attackers compromise an Mt. Gox auditor’s computer and gain admin access. 25,000 BTC stolen ($400K at the time, ~$7B today). The attacker manipulated the exchange price, causing Bitcoin to plummet from $17 to $0.01—then scooped up 2,000 more BTC in the process. Mt. Gox paused trading, restored accounts, and continued operations. But the real hack had already begun… and no one knew it yet

Thread (2/10)🧵 Mt. Gox: From Trading Cards to Bitcoin Exchange. 2006: @JedMcCaleb (yes, the guy who later co-founded Ripple & Stellar) launched Mt. Gox as a site to trade Magic: The Gathering Online cards. 2007: The site shut down after a few months, and McCaleb moved on. 2010: McCaleb saw an opportunity—Bitcoin had no easy way to be traded. So he repurposed mtgox.com into a Bitcoin exchange. 2011: Mt. Gox quickly became the most popular place to trade BTC. But McCaleb didn’t want to manage an exchange, so he sold it to Mark Karpelès (@MagicalTux) after 10 months. The deal? Mt. Gox was sold for six months’ revenue.
