The recovery is spreading unevenly

Altcoins are taking a larger role in the late-September crypto recovery. FixedFloat’s weekly roundup reported that 16 of the 100 largest cryptocurrencies had more than doubled over the previous three months, while Bitcoin had gained around 40%.

Its cited altseason index stood at 58 on September 25, up from 23 at the start of the month. That is a substantial improvement, but below the indicator’s 75 threshold for a broad altcoin season.

A handful of winners is not the whole market

The distinction matters because spectacular gains in several tokens can dominate headlines while many other assets lag. A diversified group of crypto holdings does not necessarily behave like the best performer on a chart.

The measurement window matters too. A token recovering from a deep decline can show a large quarterly percentage gain and still leave earlier buyers with losses.

Market share and returns answer different questions

Bitcoin dominance describes Bitcoin’s share of total crypto market value. An altseason index usually asks how many selected assets beat Bitcoin over a defined period.

These indicators are related, but they cannot be substituted for one another. Changes in the sample, stablecoin treatment and the comparison period can also affect the conclusion.

Watch participation, not just excitement

A more convincing broad recovery would involve sustained participation across a wider range of assets, supported by trading activity and usable liquidity. Short-lived jumps in a few names offer weaker evidence.

For now, the September data points to stronger competition for Bitcoin’s performance lead. It does not establish that every altcoin will rise or that a durable market-wide rotation has already arrived.
