The asset climbed from around $0.095 to near $0.135 before facing resistance. At the time of observation, ARB traded near $0.128, showing minor gains during the session.Crypto analyst Michaël van de Poppe addressed this trend in a recent tweet. He linked altcoin momentum to low volatility and strong Bitcoin performance. He also noted that a pullback, if it occurs, could present a buy-the-dip setup for ARB.Great momentum on #Altcoins over the past week, and given that the VIX remains low, $BTC has momentum and indices have printed new highs, I wouldn't assume that this stops.For $ARB, if this correction takes place (I doubt it), we'd likely see a buy the dip formation and… pic.twitter.com/lEGNPbzNsV— Michaël van de Poppe (@CryptoMichNL) April 18, 2026The structure still reflects higher highs and higher lows, which supports a bullish trend. However, recent rejection near the $0.135 zone slowed upward movement. Price has since entered a narrow range, indicating reduced momentum.Key levels remain in focus. Immediate resistance sits between $0.130 and $0.135, while stronger resistance appears near $0.140. On the downside, support holds around $0.125, with deeper levels near $0.120 and $0.110.Momentum indicators show a shift in pace. The Relative Strength Index moved down from overbought levels and now sits near neutral territory. This suggests easing buying pressure without clear bearish divergence.Meanwhile, the MACD indicator shows a bearish crossover with a slightly negative histogram. This points to short-term selling pressure, though not strong enough to confirm a reversal. The setup aligns more with a pause following rapid gains.Van de Poppe stated that a deeper correction remains unlikely. He added that any pullback could form a buy-the-dip pattern. His projection places a potential continuation toward the $0.16 level if support holds.Altcoin Market Cap Pulls Back After Sharp ExpansionThe broader altcoin market, excluding the top ten assets, followed a similar pattern. Market capitalization reached approximately $195 billion before retreating to near $185 billion. This move reflects a short-term correction after rapid expansion.Earlier phases showed a clear transition. The market declined through mid-March, followed by a consolidation range into early April. That phase formed a base between $169 billion and $178 billion.A breakout occurred in mid-April, with strong upward candles pushing valuation higher. The move showed limited pullbacks, signaling aggressive capital inflows during that period. However, the rally lost pace near recent highs.Current price action shows rejection near the $195 billion level. The pullback has brought the market toward a support zone between $182 billion and $184 billion. This level now acts as a key area for stability.If the market holds above $180 billion, structure remains intact. A rebound could lead to another test of the $190 billion region. On the other hand, a breakdown below support may shift focus toward $178 billion.Short-term behavior suggests consolidation may follow. A range between $180 billion and $190 billion appears likely while indicators reset. This aligns with the cooling trend seen in individual altcoins.The recent rally points to increased activity outside major cryptocurrencies. However, the sharp rejection indicates that rapid gains triggered profit-taking. The market now seeks balance after the strong move.Overall, both ARB and the broader altcoin market show similar patterns. Strong upward trends remain in place, yet momentum has slowed. Current conditions favor consolidation as traders assess the next direction.The post Altcoins Cool After Rally as ARB Holds Support and Signals Potential Continuation appeared first on Blockonomi.
