The Total3 index, which tracks the total cryptocurrency market capitalization excluding Bitcoin and Ethereum, is forming a bullish ascending triangle pattern since 2023, suggesting a potential breakout by 2026. This technical formation, characterized by higher lows and a flat resistance line, has historically preceded significant altcoin market surges, similar to the ICO boom in 2017 and the DeFi explosion in 2021. Currently, the Total3 index is valued at approximately $1.3 trillion. Analysts project that a successful breakout could propel the index to between $3 trillion and $5 trillion, as Bitcoin's dominance potentially declines from its current 55%. This anticipated growth is driven by advancements in decentralized AI, layer-2 scaling solutions, and real-world asset tokenization, alongside improving regulatory clarity globally. However, macroeconomic factors and geopolitical tensions could impact this timeline.
