Chart of the Day – Here Comes Altcoin Season

The first chart shows Bitcoin dominance locked in a massive symmetrical triangle stretching back to 2018, with Fibonacci retracement levels mapped along two eerily similar time periods: 1,092 days from 2018–2021, and 1,029 days from 2021–2025. Both cycles culminate in a tightening coil of BTC dominance, which recently kissed the upper resistance line before getting rejected. A decisive breakdown from this structure could signal an exodus from Bitcoin into altcoins, a classic trigger for altseason.

The second chart, courtesy of TechDev, backs this narrative with a textbook ascending triangle on total altcoin market cap, spanning nearly three years. Each green dot marks past cycle lows in alt market momentum, and we’ve just printed another one. If this breakout confirms, especially with the MACD crossing bullish on the higher timeframe, we could be witnessing the start of a full-blown rotation into alts. Historically, these setups have led to vertical moves, particularly as sidelined capital seeks higher beta plays following Bitcoin’s initial pump. The setup is there. The volatility is building. Now, it’s just a question of timing and whether the market gods feel like lighting the fuse.
