Where Did the Bitcoin Go?

March 2014: 200,000 BTC “found” in an old cold wallet—reducing the net loss to 650,000 BTC.

2017: Blockchain analysis traced over 300,000 BTC to BTC-e, a shady Russian exchange.

2017: Alexander Vinnik (BTC-e operator) arrested for laundering stolen Mt. Gox BTC.

2023: The U.S. DOJ indicted two Russian hackers for the original Mt. Gox theft.

Fact: This wasn’t just one hack—it was a multi-year theft & laundering operation.

February 2014 – The Collapse Begins

Feb 7, 2014: Customers couldn’t withdraw BTC—Mt. Gox suspended all withdrawals, blaming “technical issues.”

Feb 17, 2014: CEO Mark Karpelès reassured customers:
“We should be able to resume withdrawals soon.”

Feb 20, 2014: Karpelès resigned from the Bitcoin Foundation board.

Feb 24, 2014: Mt. Gox deleted all its Twitter posts, and its website went offline.

Feb 28, 2014 – Bankruptcy Filed:
•Mt. Gox finally admitted they had lost 750,000 BTC of customers’ funds + 100,000 BTC of their own.
•Total loss? 850,000 BTC (~$473M at the time, ~$40B today).

The biggest Bitcoin exchange had just vanished overnight.

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.

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.

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

The Rapid Rise of Mt. Gox

Mark Karpelès takes over (2011) and immediately doubles trading volume to ~20,000 transactions per day.

Bitcoin was trading at just $1.

By 2013, Mt. Gox handled over 70% of all BTC trading worldwide—making it the most dominant exchange on the planet.

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 https://t.co/b92gFNp5dg 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.

The Mt. Gox Bitcoin Saga: The Full Story from Day 1 to Today

Here’s the full breakdown of what happened, who was responsible, and why it still matters in 2025. 👇
