Understanding the Ethereum Flash Crash
On June 21st, Ethereum (ETH) experienced a dramatic flash crash on the GDAX cryptocurrency exchange, plummeting from approximately $319 to just $0.10 in under a second. This extreme volatility was attributed to a "multi-million dollar market sell order," triggering a cascade of automated trades that left many investors with significant losses—while one trader potentially profited over $1 million.
What Is Ethereum?
Ethereum (ETH) is a decentralized digital currency and the native token of the Ethereum blockchain. Often dubbed "Bitcoin 2.0," it distinguishes itself by supporting smart contracts—self-executing agreements coded into its blockchain. Developers use ETH to power decentralized applications (dApps), and like other cryptocurrencies, it’s traded on global exchanges.
Key Events During the Crash
- Pre-Crash High: Earlier that day, ETH had reached an all-time high of $352, capping off a 4,500% year-to-date surge.
- Trigger: A massive sell order worth millions executed at 12:30 PM EDT, filling bids between $317.81 and $224.48.
- Domino Effect: The drop activated 800+ stop-loss orders and margin liquidations, accelerating the plunge to $0.10.
- Recovery: ETH rebounded swiftly to $325, later stabilizing around $338 (per Coinmarketcap data).
Market Reactions and Controversy
The crash sparked outrage on social media, with users accusing GDAX—a Coinbase-operated exchange—of inadequate safeguards or potential manipulation. GDAX VP Adam White denied misconduct, stating:
"Our initial review found no evidence of wrongdoing or unusual account activity. We’re committed to a full investigation."
All trades were declared final, though ETH trading was temporarily halted post-crash for system repairs.
The $1 Million Windfall?
Amid the chaos, trader John DeMasie shared a screenshot (unverified by CNBC) showing a buy order for 3,800 ETH at $0.10. If legitimate, this $380 investment would’ve ballooned to **$1+ million** upon rebounding to $300+.
