ETC Surges 8.6% After Core-Geth Security Incident
Ethereum Classic (ETC)

tradersunion.com reports that Ethereum Classic climbed 8.59% following a swift response by mining node operators to a social engineering attack. On September 14, a fraudulent version of the Core-Geth client was distributed as a security update across official channels. Some miners upgraded to this fake software before reverting to the legitimate version, restoring network stability.
The rebound is supported by ETC trading above its short-, medium-, and long-term moving averages. Specifically, the price sits above the 20-day, 50-day, and 200-day averages at $7.5765, $7.1218, and $7.78265 respectively. This positioning signals bullish momentum despite the MA-50 alignment trailing the MA-200.
Immediate support is defined at $8.06 by the Ichimoku Kijun, with resistance set at the session high of $8.14. Momentum indicators show mixed signals, with MACD and ADX in buy territory but RSI at 49.86 with a sell outlook. The Stochastic RSI is in oversold territory at 17.87, while the CCI is neutral at -47.07.
Analysts note that upward momentum exists amid diverging technical signals and heightened volatility. Traders are advised to monitor the $8.14 resistance as a potential catalyst for further upside if breached.
How the market reacted
Whalio's own Binance spot order flow for ETC, measured when this story was written up on 18 September 2026. Not the outlet's figures.
Whalio data shows ETC trading at $7.52 with a 1-hour buy ratio of 40.3%, indicating immediate selling pressure. However, the 4-hour buy ratio is 51.9%, suggesting that buying pressure is building over a slightly longer timeframe compared to the short term. The 24-hour buy ratio stands at 51.4%, showing that buyers have maintained control over the full day. Volume delta reflects this shift, moving from a -$11,999 outflow in the last hour to a +$40,883 inflow over four hours. Over 24 hours, the volume delta is +$63,478, meaning more money flowed into buys than sells. Cumulative Volume Delta closed at -$81,918, indicating that despite recent buying, net selling pressure dominated the day's close. Spot volume reached $2,155,907 with 17,935 trades, showing active participation.
The latest daily buy ratio of 47.1% sits at the 28th percentile of the last 322 days, against a median of 49.0% - weaker buying than most days.
Was that an ordinary day?
The same Binance spot measurements for ETC, averaged over the days leading up to the story.
Over the preceding week, ETC saw a 7-day average buy ratio of 52.0%, slightly higher than the current 24-hour reading of 51.4%. This represents a -0.6 point difference, indicating a marginal decrease in buying intensity compared to the weekly norm. Volume was 0.88x the average, showing reduced trading activity relative to typical days. Net buying occurred on 6 of the last 7 days, with a total volume delta of +$562,468 over 8 days. The price changed -0.8% over 8 days, suggesting a slight decline despite the recent surge. This day appears ordinary in terms of buy ratio but unusual due to lower volume compared to the weekly average.
