Bitcoin has slipped back to about $76,500 after stalling near $80,700 in August, and traders are calling the round-trip a "Bart Simpson" chart pattern. Analysts warn a completed pattern could drag the price toward $70,000 or lower, just as the Federal Reserve's September 15-16 meeting adds fresh uncertainty.
Bitcoin's failure to clear resistance near $80,700 has crypto traders invoking "Bart Simpson," the spiky-haired cartoon character, as a warning sign for further declines. The chart formation — a sharp rally, a flat stretch, then a steep reversal — resembles the shape of Bart's hairline when plotted on a price chart.
A pattern traders haven't seen in years
The move began Aug. 19, when bitcoin traded around $64,420, then climbed to roughly $78,300 by Aug. 21 before topping out just under $80,700 on Aug. 25. It has since drifted back to around $76,500. Mati Greenspan, founder of Quantum Economics, said the setup only counts as a genuine Bart Simpson pattern if price falls at least 20% from the peak. According to CoinDesk: "It's only a Bart Simpson if it falls 20%." Greenspan added that thicker liquidity and greater institutional participation have made the pattern rarer in bitcoin's price action than in years past.
Analysts flag $70,000 and $58,000 as downside targets
Frank Hepworth, CEO of New Market Trading, called the current chart a distribution pattern, pointing to bitcoin's repeated rejection at its 50-week moving average near $81,000. Because bitcoin failed to clear that level, Hepworth warned the market could slide back toward $70,000, or as low as $58,000 if selling intensifies, prompting his firm to trim exposure.
Fed decision and ETF flows loom over the next move
The Federal Reserve meets on Sept. 15-16, and markets currently price a 68% probability of a rate hike from the current 3.50%-3.75% target range, against a 32% chance rates hold steady. A hike would likely lift Treasury yields and strengthen the dollar, adding pressure on bitcoin. Coingape reported bitcoin's nearest support sits around $75,000, with a break below exposing the $68,000 breakout zone, while a recovery above $80,000 would put $82,000 and then $85,000 back in view. Spot bitcoin ETFs pulled in about $3.5 billion in August, the strongest monthly inflow since July 2025. Since then, net outflows reached $236 million as of Sept. 1.
The Aug. 19 rally traces back to the Treasury Department's move to double liquidity-support buybacks for longer-dated government debt, from $2 billion to $4 billion per operation, which sent bitcoin, gold and stocks higher together. Whether that rally completes its Bart Simpson shape now hinges on the Fed's next move.
