Analysts are leaning bullish on altcoins as March begins, pointing to improving technical structure and a shift in momentum that echoes early phases of past expansion cycles. Multiple on-chain traders and chartists say the conditions look similar to the setup that preceded the broad alt rallies of previous years.
Pseudonymous trader Chain Mind highlights that altcoin dominance—led by tokens such as XRP, BNB, Solana, Cardano and Tron—has broken a long-term downtrend and monthly momentum has flipped higher. Chain Mind notes comparable signals showed up in 2020 before a broad altcoin advance and suggests the current configuration could precede a larger rotation and a possible next “altseason.”
Other commentators provide reinforcing data. Nunu observes that only about 5% of altcoins sit above their 200-day moving average, a reading historically associated with washed-out conditions rather than an overheated market. Nunu also points to whale accumulation in UNI and BCH and emerging breakout setups in ASTER, ARB and APTOS. Large token unlocks for SUI, ENA and HYPE are approaching, events that can reallocate liquidity and change short-term dynamics. At the same time, Ethereum dominance appears to be rolling over, which some traders interpret as capital shifting from large-cap assets into higher-beta altcoins.
CryptoSymbiiote adds that many altcoins have bounced off a year-long support trend line, projecting the next three to six months as a potentially explosive window for returns if momentum continues to build.
That said, broader market indicators still favor Bitcoin dominance for now. CoinMarketCap’s Altcoin Index sits at 36/100 (up from 31 last week and 32 last month), well below this year’s high of 78 recorded on September 20, 2025. Dispersion of performance remains pronounced: over the past 90 days RIVER is up roughly 250.19%, PIPPIN 155.07% and KITE 149.69%, while larger tokens like TRX have gained under 1% in the same period.
Market observers stress that for March to mark the start of a sustained altcoin resurgence, dominance and market breadth must continue to improve—meaning more altcoins moving above key moving averages, rising monthly momentum, and broad participation rather than isolated winners. If those conditions materialize, the next few months could favor a wider rotation into altcoins; if not, Bitcoin’s relative strength could keep the cycle tilted toward larger-cap leaders.
