Altcoin Index flashes Bitcoin season – Why THESE signals say otherwise

Is the market manipulating on-chain signals?

Interestingly, the Altcoin Season Index is set to close August at around 29 points, just four points away from full-blown Bitcoin season. The key takeaway? The index is down 56% from its early-August peak of 67, showing that altcoin momentum has weakened significantly over the month.

But the technicals tell a different story. As the chart below shows, TOTAL2 (total market cap excluding Bitcoin) has gained over 17% during the same period, while Bitcoin dominance increased by just over 2%. Thus, the altcoin market grew more than 8x faster than the increase in Bitcoin dominance. This suggests that funds are flowing into altcoins at a much higher rate than suggested by the Altcoin Season Index.

Naturally, this begs the question: Is the index giving a misleading signal on altcoin strength?

According to the Altcoin Season Index, the last major altcoin rotation was seen in mid-May, when the index dropped to 22. What followed was a two-month run-up in altcoins, while Bitcoin dominance faced multiple rejections at the 60% level. Fast-forward to now, and the index is only 7 points above the same low, yet the technicals are telling a very different story, with TOTAL2 holding strong.

Meanwhile, technical weakness, macro FUD, and weak on-chain signals are weighing on Bitcoin [BTC]. Should Bitcoin dominance face another rejection at the key resistance zone, the setup is favorable for a May-like altcoin rally. In that case, the sharp drop in the Altcoin Season Index can be interpreted as a false signal ahead of another rotation into altcoins.

Bitcoin dominance hits resistance as altcoin rotation builds

The market seems to be going against the Altcoin Season Index.

Technically, it seems that market players are increasingly confident that an altcoin rotation is near. Importantly, it appears that the technical signs point to the fact that the altcoin rotation is beginning to take off. This is because capital has already begun rotating into altcoins despite the index flashing Bitcoin season.

Meanwhile, macro FUD is back, with Brent crude jumping over $90 as U.S.-Iran tensions escalate. This adds pressure to Bitcoin’s setup, especially with trading volumes still near three-year lows. As the chart below shows, Binance spot volumes dropped from $198 billion to roughly $44 billion, while Gate and Bybit also saw roughly 70% declines. This weak participation suggests that Bitcoin still lacks strong conviction despite its 30%+ August rally.

Taken together, these signals help to understand why Bitcoin’s setup is increasingly weak.

Not to mention that the timing is now close to the previously observed patterns. Bitcoin dominance is once again testing the 60% level, and with the mix of macro factors and weak volumes, it is plausible to expect another rejection. This development would almost certainly trigger a stronger altcoin rotation, similar to what happened in late May.

Final Summary

• BTC dominance is testing 60% resistance again, while weak volumes and macro pressure leave room for another rejection.
• A rejection could trigger a May-style rotation into altcoins, even as the Altcoin Season Index continues to flash Bitcoin season.
