The crypto world is like a stormy ocean, where Ethereum often plays the role of the big waves – calm one moment, destructive the next. Today, October 21, 2025, opening the ETHUSD chart, I sense the market gathering its breath after a sudden drop. The daily candle opened at $3,980.74 in GMT, but now it's at $3,871.85, down about 4.3%. This move looks more like a technical correction than a paradigm shift, and it might be just what was needed to clean out weak positions. Let's dive into the key levels first, as they serve like signposts in this chaos. The main support is at $3,867, aligning with the classic S2 pivot point and recently acting as a temporary floor. If ETH holds above that, buyers might step up and push toward the first resistance at $3,901. That's where sellers have flexed their muscle lately, but it hasn't been fully tested. Higher up, $3,909 to $3,922 awaits, and breaking that could unlock $4,000 and even $4,100. Sure, if support breaks, we could slide to $3,859 or lower, but October tends to be kind to altcoins – especially with institutional money flowing in. The indicators tell an intriguing story too. The 14-period RSI sits at 34.452, below 50 and smelling of oversold conditions. Sellers are likely tiring, and this could be an early buy signal, particularly if RSI pushes above 50. MACD at -28.37 has the signal line below the main line, but its histogram is shrinking – a hint that downside momentum is losing steam. The 50-day moving average is at $3,973 and the 200-day at $3,986, both easing off gently, confirming short-term pressure while keeping the broader uptrend intact. Volume has spiked on sells, but ETF inflows could shift the balance. Imagine it: markets are always full of unexpected twists. Remember how in September 2025, after network upgrades, ETH surged to $4,200? Now, with macro pressures like interest rates, the market hoped for $5,000, but this dip feels like a pit stop for refueling. Some experts think it's just flushing excess leverage, and ETH is oversold against BTC – the ETH/BTC ratio at monthly lows. These are signs whispering, hang in there, the next wave is coming. Of course, risks aren't absent. If inflation spikes or whales sell more, we might hit $3,800. But the Fear & Greed Index around 32 (moderate fear) often precedes turnarounds. Chart patterns show a short-term descending channel, but the lower boundary at $3,867 holds support. Bollinger Bands have price hugging the lower edge, leaving room for a snap back to the middle. All in all, this analysis sees short-term caution but long-term upside. Traders could wait for consolidation above $3,901 before going long, with a stop at $3,867. For holders, this dip is prime adding territory. Markets rise and fall, but Ethereum, with its vast ecosystem, always bounces back. Bottom line, the practical tip is: keep an eye on the charts, but don't rush. A solid correction can launch us to higher ground. If we hold $3,871 today, tomorrow might greet $3,950.
