The altcoin market is holding firm above a significant 8-year trendline support, as the 2024 all-time high is being retested. The TOTAL2 index, which tracks altcoins excluding Bitcoin, remains stable at this critical technical level, suggesting a robust macro outlook for altcoins. Analysts view the retest of the 2024 ATH as a typical market behavior rather than a sign of weakness. Continued institutional interest, advancements in Web3, and favorable regulatory developments are bolstering a positive market sentiment.
