The crypto market enters a busy stretch, making this one of the most important weeks for altcoins to watch. Network upgrades, ETF decisions, and major token unlocks are setting the tone as traders look for fresh momentum after October’s sharp swings.
Three altcoins to watch this week are flashing clear setups – some hinting at recovery, others testing key supports. From structural upgrades to regulatory catalysts, this week’s events could decide whether altcoins extend their rebound or face another correction.
COTI (COTI)
The first on the list of altcoins to watch this week is COTI, which completed its Hydrogen upgrade just a few hours ago. The upgrade aims to improve speed, scalability, and network security, giving COTI a stronger foundation for growth.
Since the rollout, COTI has gained nearly 7%, hinting at early optimism among traders. On the chart, the token trades between $0.037 and $0.031.
The first key breakout level is at $0.040 — about 15% above current prices. A move above that could send COTI toward $0.055, its next key resistance zone.
Between October 11 and 19, price formed a lower low while the RSI or Relative Strength Index indicator (a tool that tracks buying and selling momentum) formed a higher low, creating a bullish divergence. If the network maintains its speed and stability after the upgrade, that divergence could fuel a short-term reversal.

If the price falls below $0.031, the bullish outlook fades, and COTI could test new lows. Still, with improving fundamentals and signs of recovery on the chart, COTI stays one of the altcoins to watch this week.
Cardano (ADA)
Cardano is one of the top altcoins to watch this week, with the ETF buzz giving the project a clear near-term catalyst. The odds of a US spot Cardano ETF approval have surged to 89%, with a final SEC decision expected by October 26.
If approved, it would be a major moment for ADA, allowing institutional exposure similar to Bitcoin and Ethereum ETFs.
On the charts, Cardano still trades inside an ascending channel, taking support from the lower trend line. The last three daily candles show renewed buying interest, hinting that the strength behind the recent bounce isn’t misplaced — likely influenced by the ETF optimism.
The key resistance level to watch is $0.73, which ADA needs to break to confirm short-term strength. If it clears that zone, ADA could push toward $0.86, a level that has capped multiple rallies since late September.
A close above $0.86 could set up a breakout toward $1.12–$1.14, breaking the channel’s upper boundary and opening space for new highs.
From current levels, ADA needs roughly a 29% rally to reach $0.86. If the ETF approval goes through and market sentiment stays positive, that move looks plausible. However, if the $0.61 support breaks, $0.59 and $0.50 could come into play, invalidating the bullish setup.
With ETF anticipation rising and technicals aligning, Cardano remains one of the most important altcoins to watch this week — both for its potential breakout and how it reflects the broader market’s appetite for regulatory-backed crypto exposure.
Toncoin (TON)
Toncoin is another strong contender among altcoins to watch this week, mainly because of the upcoming $80 million token unlock scheduled for October 23, according to DefiLlama data.
Token unlocks of this size often create short-term uncertainty, as new supply enters circulation and could increase selling pressure.
Despite the looming unlock, Toncoin has gained nearly 6% in the past 24 hours. This shows notable resilience and even broader market outperformance.
Still, the chart structure remains cautious. TON is trading inside a descending triangle. And that’s a pattern that typically signals indecision or possible downside if key supports (bases) give way.
The important Fibonacci levels (bases) to watch are $2.15, $1.77, and $1.30. Right now, $2.15 acts as strong support. If that level breaks, TON could slide to $1.70, a potential 21% correction, and further down to $1.30 if momentum weakens.
On the other hand, reclaiming and holding above $2.53 could invalidate the bearish outlook and open the way for a rally toward $3.07.
