A second MACD bullish crossover is signaling potential gains for altcoins, with Solana, Tezos, LayerZero, Uniswap, and SPX6900 emerging as key contenders. Historically, such crossovers have marked the onset of altcoin dominance phases, though traders are advised to maintain risk management strategies as technical signals do not guarantee outcomes. Solana (SOL) is showing resilience with price action above key moving averages, while Tezos (XTZ) is recovering from long-term support levels. LayerZero (ZRO) is gaining traction as a promising infrastructure token, and Uniswap (UNI) benefits from strong liquidity metrics. SPX6900, known for its volatility, presents speculative appeal but requires cautious handling due to its high-risk profile.
