Key Takeaways
Altcoins are beginning to show signs of strength as BTC.D weakens. Netflow data points to investors pulling select tokens off exchanges.
Markets are starting to show some subtle but telling shifts.
Experts are watching certain altcoins closely, while dropping Bitcoin [BTC] dominance and rotation signs point to something cooking.
It’s too early to call it outright, but the data may be pointing toward an interesting phase ahead for the market.
Outflows put FET, AMP and SNX in the spotlight
Data from Binance’s altcoin netflow chart is showing a change in trader sentiment.
Analyst Burakkesmeci noted that coins like Fetch.ai [FET], Amp [AMP], and Synthetix [SNX] saw some of the strongest outflows going into the second week of September.

Large outflows typically suggest that investors are moving tokens off exchanges, often a bullish sign as it indicates holding rather than selling.
In contrast, tokens like Polygon [MATIC], Chiliz [CHZ], and Sui [SUI] are showing strong inflows, which could mean more selling pressure ahead.
Altcoin season index goes higher
Another sign backing the trend comes from the altcoin season index, which climbed to 61 at press time.

Anything above 50 says the market is tilting away from Bitcoin and leaning toward altcoins. Whenever this index pushes higher, traders tend to rotate their focus into smaller-cap tokens in search of stronger gains.
While it’s not a full-fledged “altcoin season” yet, the recent lift shows that momentum is slowly shifting.
An incoming shift
At press time, Bitcoin’s dominance [BTC.D] stood at 58.38%, near key support levels.

Patterns show that sharp drops in BTC dominance often cause strong altcoin rallies.

Analysts like AshCrypto also have a similar view, posting on X that the market could be just 4–6 weeks away from a major rotation.
He pointed to a possible “mega altseason” between October and March, with billions expected to flow into altcoins if the trend holds.
While nothing is guaranteed, the data says the tide may be slowly turning in favor of altcoins.
