Key Takeaways
September was a mixed month for the crypto market. While Bitcoin (BTC) reached a positive close, numerous altcoins crashed, retracing months of upward movements.
However, there are some exceptions to the norm, which will likely lead to gains in October once the market stabilizes.
This article will analyze three altcoins with bullish setups against BTC that can post significant gains in October.
The SOL price fell after reaching its cycle high of ₿0.00310 in March 2024.
Its decline continued for over a year, leading to a low of ₿0.00125 in June 2025, a drop of more than 60% since the cycle high.
However, the fortunes have shifted since then. The SOL price began an upward movement after creating a double bottom pattern, reclaiming the ₿0.00185 horizontal resistance area.
Last week, the SOL price declined, but bounced at the horizontal area (green icon), confirming it as support.
This is a customary retest after the breakout, suggesting the price will likely increase.
To confirm this possibility, the SOL price has to break out from its diagonal resistance, which has existed since the cycle high.

Momentum indicators support the breakout possibility. The Relative Strength Index (RSI) and Moving Average Convergence/Divergence (MACD) have created bullish divergences (orange).
The RSI is above 50, while the MACD is positive, both signs of a bullish trend.
As a result, the SOL price is likely to break out, gradually increasing toward the cycle high resistance of ₿0.0030.
The SUI price began a recovery against Bitcoin in June, but that was short-lived.
In July, the SUI price began a downward movement that is still ongoing.
However, despite this decline, numerous bullish signs are developing.
Firstly, the SUI price trades inside a descending wedge, a bullish pattern that usually leads to a breakout.

Secondly, it has bounced at the 0.618 Fibonacci retracement support level, an area that often leads to bullish trend reversals.
Finally, the SUI price has completed an A-B-C correction (red), after which another upward movement is likely.
If a breakout occurs, the SUI price could reach a high of at least 4,000 satoshis, increasing by more than 40%.
The final altcoin that can outperform Bitcoin in October is ZEC, which has already begun its upward movement.
The ZEC price has surged by over 300% since the start of September, and has broken out from the 80,000 satoshi horizontal resistance area.
The resistance has existed for over two years, so a decisive breakout above it could lead to a parabolic upward movement of another 65%, reaching the 210,000 satoshi resistance.

The RSI and MACD support this rally, since the former just crossed above 70 while the latter is positive.
The most rapid increases often occur once the RSI crosses 70, so the indicator readings align perfectly with the bullish ZEC price analysis.
Altcoins like Solana, SUI, and Zcash show strong bullish setups that point to further upside against Bitcoin.
SOL has reclaimed key support, SUI is nearing a bullish breakout from a descending wedge, and ZEC has surged through long-term resistance.
If the trend continues, these three altcoins could lead the market in October, offering stronger gains than BTC.
