Over the past seven days, Ether (ETH), XRP (XRP) and Solana (SOL) have gained 44.3%, 20.6% and 22% respectively, compared to BTC’s 10% rise. Complementing the recovery with a deeper analysis, crypto trader ZERO IKA observed that many altcoins have formed a higher time frame break of structure above their February and March highs. The analyst noted that despite recent upside, most altcoins remain 70% to 90% below their all-time highs, indicating a “relatively early” opportunity for a recovery. The weakening stablecoin and Bitcoin dominance, coupled with a rise in altcoin market cap, opens the door for an altseason, as long as the above key trends remain intact.
