A potential altcoin season is on the horizon as market dominance patterns mirror those seen in 2017 and 2021, according to recent TradingView data. Analyst MikybullCrypto highlighted the "Crypto Total Market Cap Excluding Top 10 Dominance" chart, which currently stands at 7.60% as of May 23, 2026. This metric has historically signaled major crypto market rallies when similar structures emerged in past cycles. The analysis suggests that capital rotation from large-cap to smaller cryptocurrencies could drive a broader altcoin rally. Historically, declines in top token dominance have preceded increased participation from smaller assets. As Bitcoin dominance weakens, investors may shift towards higher-risk altcoins, potentially igniting a new market expansion phase.
