On April 26, 2023, Bitcoin experienced a dramatic flash crash that wiped out billions in market value within minutes, sending shockwaves through the cryptocurrency market. The flagship digital currency plunged approximately 7% in just one hour, falling from around $29,850 to a low of $27,789 before partially recovering to trade near $28,422.
TL;DR
- Bitcoin dropped 7% in a single hour on April 26, 2023, falling from $29,850 to $27,789
- Rumors linked the crash to an Arkham Intelligence alert about US government and Mt. Gox wallet movements
- Arkham denied sending erroneous alerts, claiming the notification was dispatched after the crash
- The US government still held approximately 198,000 BTC worth roughly $23.5 billion at the time
- ETH also suffered sharp losses, declining from multi-month highs above $2,100
The Crash That Stunned the Market
The sell-off began abruptly during the morning trading hours, catching many traders off guard. Bitcoin had been showing strength in the days prior, even briefly touching the $30,000 mark earlier on April 26. The sudden reversal erased those gains and then some, triggering widespread liquidations across derivatives markets.
Ethereum was not spared either. The second-largest cryptocurrency had reached a multi-month high above $2,100 on April 25, but the cascading sell-off dragged ETH down sharply alongside Bitcoin. By the end of the day, ETH was trading around $1,866, reflecting a significant pullback from its recent peaks.
The Arkham Intelligence Controversy
In the immediate aftermath, attention turned to blockchain analytics platform Arkham Intelligence. A widely followed crypto news alert account on Twitter known as DB, or tier10k, posted that addresses linked to the United States government and the defunct Mt. Gox exchange were moving significant amounts of Bitcoin.
The claim triggered immediate panic selling. Traders feared that the US government was preparing to liquidate seized Bitcoin holdings, while Mt. Gox creditors might finally be receiving their long-awaited repayments. Both scenarios would introduce substantial selling pressure to the market.
Arkham initially acknowledged that a bug fix on their platform had caused an alert to be sent erroneously to a small subset of users. However, the company later reversed course, issuing a statement that an internal investigation determined the alerts were sent accurately.
What Actually Happened
According to Arkham’s detailed explanation, DB had configured personal alerts on the platform for Bitcoin transactions exceeding $10,000, labeling them “Mt Gox” and “US Gov.” When an on-chain event triggered these alerts, DB inferred that the actual Mt. Gox and US government wallets were active and tweeted accordingly.
Arkham clarified that the US government wallet associated with Silk Road hack funds did witness a transaction on April 26, but it was an inbound transfer worth merely $0.19 — hardly the massive sell-off the market feared. The company also stated that the alert was sent minutes after the market crash had already concluded, challenging the narrative that their notification triggered the sell-off.
Some blockchain observers speculated that Ordinals inscriptions on the relevant addresses may have made them appear active without actually moving funds, potentially triggering the automated alerts.
Government Bitcoin Holdings Remain Intact
Despite the market panic, Arkham confirmed that the US government continued to hold at least 198,000 BTC across multiple agencies and wallets, valued at approximately $23.5 billion at the time. No evidence emerged of any coordinated government sell-off.
The incident highlighted the outsized influence that on-chain monitoring tools and social media accounts wield over cryptocurrency markets. A single misinterpreted alert was enough to trigger billions in forced liquidations and panic selling across the digital asset ecosystem.
Why This Matters
The April 26 flash crash serves as a stark reminder of the fragility of crypto market sentiment. Despite Bitcoin’s maturation as an asset class, the market remains highly susceptible to misinformation cascading through social media channels. The episode also underscores the growing importance of blockchain analytics platforms like Arkham Intelligence, whose alerts — accurate or not — can move markets worth trillions of dollars in minutes.
For traders and investors, the incident reinforces the need for independent verification of on-chain claims before acting on social media reports. It also raises important questions about the responsibility of analytics platforms and crypto influencers in preventing market-disrupting false alarms.

7pct in one hour was almost entirely futures liquidations cascading. spot selling was maybe 1.5pct of the move. leverage was insane at 29K
liquidation_map_ 1.5pct spot selling causing a 7pct drop tells you the order book was tissue paper at 29K. same structure at every local top
liquidation_map_ the 7pct cascade was almost entirely futures getting wrecked. spot sellers were maybe 1.5pct of the actual move. leverage does the rest
Tariq S. 1.5% spot selling causing a 7% move is why liquidation cascades are the real market structure. spot sellers barely moved the needle, leverage did everything
7% in one hour over a false alarm. this market is held together by bots and vibes
wasn”’t false, arkham just covered their tracks. the wallets actually moved, timing was the dispute
bots and vibes is the most honest description of crypto market structure ive ever seen. 7% dump on a notification with zero verified data
bots and vibes is the most accurate description of crypto market structure ive ever read
7% over a false alarm and it recovered within hours. imagine what happens when the gov actually starts selling those 198k btc
198k btc sitting in gov wallets is a constant overhang. any movement spooks the market instantly
every time those wallets twitch the market dumps first and asks questions never. classic sell first think later dynamic
198K BTC in government wallets is the ultimate overhang. every time those wallets sneeze the market dumps 5 to 7% before anyone checks if the transfer was real
Arkham denied sending the alert but their notification showed up on everyones phone at the same time as the crash. convenient timing
the timing was too perfect. arkham alerts go out, market dumps, then they say oops wrong timing. yeah right
innovation continues despite market conditions
Arkham alert timing debate misses the point. 198K BTC in government wallets is a permanent overhang. every false alarm is a preview of the real dump
198K BTC in government wallets and every false alarm is a stress test for the real thing. when they actually start selling the cascade makes this look like a blip
