In 2014, Mt. Gox — the biggest Bitcoin exchange in the world — collapsed overnight. Traders logged in to find their balances gone, as the company admitted a jaw-dropping 850,000 bitcoins had disappeared. Back then, the loss was worth $450 million. But at today’s price of $114,000 per coin, those missing BTC add up to a mind-bending $100 billion.
The theft didn’t happen in one dramatic hack. For years, coins were quietly drained from Mt. Gox wallets while customers kept trading as if nothing was wrong. It was a slow bleed that no one at the top seemed to notice — until the entire exchange crumbled in chaos.
Investigators followed the digital trail and found huge amounts of the stolen Bitcoin flowing into wallets tied to Alexander Vinnik, a Russian national. He ran the shadowy BTC-e exchange, which became the laundromat for billions in dirty crypto. Authorities say Vinnik was at the heart of the laundering machine that cleaned up the Mt. Gox fortune.
His arrest in 2017 turned into an international tug-of-war, with the U.S., France, and Russia all fighting to put him on trial. While creditors are only now seeing scraps of repayment, the fallout from Mt. Gox still haunts the crypto world more than a decade later.
Trader accidentally swaps $50M $USDT for $36,000 $AAVE on Ethereum.… And an MEV Bot Walked Away With $9.9M
Here’s the story 👇
🧵 20 Days Ago
A fresh wallet received $50.4M USDT from Binance.
No one knew what the wallet was planning.
Fast forward to today…
💥 The $50M Swap
The wallet attempted to buy AAVE using the entire $50M USDT through the Aave interface.
But there was one major problem:
The order was massive relative to available liquidity.
The interface warned about extreme slippage and required the user to manually confirm a checkbox acknowledging the risk.
The user confirmed it on mobile.
Then executed the trade.
📉 The Result
Instead of receiving ~$50M worth of AAVE…
The user only received ~327 AAVE.
Total value received: about $36K.
That implies an effective price of ~$154,000 per AAVE.
The swap was routed through CoW Protocol and executed via SushiSwap liquidity.
🤖 Enter the MEV Bot
Within the same block, an MEV bot spotted the opportunity.
Here’s what it did:
1️⃣ Flash borrowed $29M WETH from Morpho 2️⃣ Bought AAVE at fair market value via Bancor 3️⃣ Dumped that AAVE into the distorted SushiSwap pool created by the user’s trade 4️⃣ Repaid the flash loan
Final profit?
💰 $9.9M in a single block.
⚠️ What Happened Here
Nothing was hacked.
The problem was liquidity, slippage, and transaction size.
Everything technically worked exactly as designed.
The problem was liquidity + slippage + transaction size.
When a $50M order hits a thin liquidity pool, the price curve explodes.
MEV bots are constantly scanning for these inefficiencies.
And when they appear…
They extract value instantly.
🏗️ Aftermath
The team behind the routing acknowledged the outcome was far from optimal, despite the user confirming the warning.
They’ve stated they will:
• Attempt to contact the user • Return $600K in fees generated from the trade • Explore additional guardrails for large swaps $AAVE $BTC
The chart shows a clear bearish structure with price trading under strong resistance and forming lower highs and lower lows. Selling pressure remains dominant as the market continues to move downward after rejecting higher levels. This movement suggests that sellers are in control and the momentum favors further decline in the short term. If the current bearish trend continues, the price may move toward the first target at 66,240. A strong break below this level could open the path toward the second target at 65,044, where temporary support may appear. However, if selling pressure persists, the market may extend the decline toward the third target near 63,024. Traders should watch for confirmation signals and manage risk carefully as volatility may increase around these key support zones. $XRP $BTC
PayPal, with over 400 million active accounts, is adding cryptocurrency support to its peer-to-peer (P2P) payments, allowing users to send and receive digital assets directly—a move that could speed up mainstream adoption beyond just investment and trading.
The company introduced PayPal Links, a personalized one-time link generated in the app that can be shared across text, email, or chat. The feature will launch first in the US, then expand to the UK, Italy, and other markets later this year.
Soon, users will be able to send cryptocurrencies and stablecoins through PayPal’s P2P feature, both to PayPal and Venmo users, as well as to compatible wallets. Supported assets include Bitcoin (BTC), Ethereum (ETH), PYUSD, and more.
