According to Crypto Rover, altcoins have decisively broken out of a 140-day downtrend, signaling the first real indication of a potential utility season for alternative cryptocurrencies (source: Crypto Rover, Twitter, April 28, 2025). This technical breakout is considered a major bullish indicator for traders, as prolonged downtrends often precede periods of strong price action and increased trading volume in the altcoin market. Traders are advised to monitor key resistance and support levels for top altcoins, as this breakout could lead to significant rotation from Bitcoin into high-utility tokens if momentum continues (source: Crypto Rover, Twitter).
