A striking resemblance between the TOTAL3 altcoin market structure and a historic 2020 pattern hints at an explosive breakout in the near future. The index, which measures the market cap of all altcoins excluding Bitcoin and Ethereum, is nearing $1.3 trillion resistance. This level echoes past rejection points from 2021 and early 2025, suggesting a potential repeat of historical patterns. The market structure shows a rounded bottom formation similar to that observed between 2018 and 2021, further supporting the anticipation for an explosive rally. The bullish momentum is fueled by several factors: a recent bull flag breakout, MACD crossover, and tightening price action beneath the crucial $1.3 trillion level.
