A man stole 120,000 Bitcoin worth $71 MILLION, recruited his wife to launder the fortune, watched it grow to BILLIONS, and was linked to the crime after his wife spent a $500 Walmart gift card bought with Bitcoin. > In August 2016, Ilya Lichtenstein hacked Bitfinex, one of the world’s major cryptocurrency exchanges. > He used unauthorized transactions to steal 119,754 Bitcoin. > At the time, the Bitcoin was worth approximately $71 MILLION. > He then recruited his wife, Heather Morgan, to help launder the stolen fortune. > Morgan had a public career writing about business and cybersecurity, including articles for Forbes. > She even wrote an article for Forbes offering advice on how businesses could protect themselves from cybercriminals. > She also made rap videos under the name “Razzlekhan,” calling herself the “Crocodile of Wall Street.” > Meanwhile, the couple moved the stolen Bitcoin through cryptocurrency exchanges, fake identities and other methods to hide where it came from. > But in May 2020, investigators uncovered a small transaction that helped connect the money to Morgan. > Someone had used Bitcoin linked to the stolen funds to buy a $500 Walmart gift card. > Parts of the card were redeemed through Walmart’s app using Morgan’s name and email, with the couple’s apartment address used for deliveries. > Investigators followed the trail to their digital accounts. > On January 31, 2022, authorities decrypted a file in Lichtenstein’s cloud storage containing thousands of cryptocurrency addresses and their private keys. > Those keys helped investigators seize approximately 94,636 bitcoin:native worth $3.6 BILLION at the time. > The couple were arrested in February 2022. > In November 2024, Lichtenstein was sentenced to five years in prison, while Morgan received 18 months. > Both were released early. > Morgan was released in 2025, while Lichtenstein was transferred to home confinement in January 2026. She wrote about protecting businesses from cybercriminals, made rap videos as Razzlekhan, and helped launder Bitcoin from one of the biggest crypto thefts in history. But a $500 Walmart gift card helped investigators connect the dots.

If you think you've made an expensive mistake, wait until you hear this. In March 2022, an NFT collector tried to sell EtherRock #44# for 444 $ETH, worth around $1.2 MILLION at the time. But he accidentally entered 444 wei instead, listing it for less than a cent. A trading bot bought it almost immediately. The collector, known as Dino Dealer, said the mistake had cost him his entire net worth. The buyer later resold EtherRock #44# for 234 $ETH, worth roughly $548,507 at the time. He tried to sell an NFT for over $1 MILLION but accidentally let it go for less than a penny. Could you ever get over a mistake like this?

If you think you've made a crazy mistake before, then you haven't seen this. In November 2017, a developer accidentally destroyed a piece of code that 587 Ethereum wallets depended on. One mistake froze 513,774 $ETH worth over $150 MILLION at the time. Among the victims were the funds raised in Polkadot's ICO. Its wallet held 306,276 $ETH, now worth $717.92 MILLION. The $ETH is still sitting in the wallet, visible to everyone, but the funds remain inaccessible. And the developer's explanation on GitHub was "I accidentally killed it." Could you live with making a mistake that expensive?

A college student caused a dorm-wide blackout mining Ethereum, then dropped out to build a blockchain backed by Mark Cuban. > Eric Chen was studying at NYU when he got into crypto. > He started mining Ethereum in his dorm room. > The mining consumed so much power that it caused a dorm-wide blackout. > Eric ended up facing NYU's disciplinary board. > But the incident didn't push him away from crypto. It pulled him deeper into blockchain research. > He also worked at a trading firm, studying financial markets. > He noticed a problem with decentralized exchanges. They were vulnerable to front-running, where traders could exploit pending transactions. > Eric wanted to fix that. > In 2018, he teamed up with Albert Chon to build Injective. > They wanted to make decentralized trading fairer and more efficient. > But building the technology proved harder than expected. > The team explored ways to solve front-running without making trading slower or more expensive. > Then they heard about Binance's first-ever incubation program. > They were traveling when they learned applications were open. > They canceled the rest of their trip and focused on getting accepted. > Binance Labs selected them, giving Injective an early breakthrough. > In 2021, they cold-emailed Mark Cuban, connecting Injective's vision to the GameStop trading controversy. > Cuban replied, and eventually joined Injective's $10 MILLION Series A round. > Injective grew into a blockchain built specifically for financial applications. A student who once caused a blackout mining Ethereum went on to build financial infrastructure backed by Mark Cuban. Imagine if he'd decided crypto wasn't worth the trouble.
