The crypto market is moving cautiously, but beneath the sideways price action, several altcoins are approaching key decision points. With supply events, network catalysts, and shifting on-chain behavior in play, the coming days could bring sharp moves if control flips to buyers or sellers.

Here are three altcoins to watch in the third week of December, each with a clear technical and fundamental trigger.

Sei (SEI)

SEI remains under sustained pressure as December progresses. The token is down nearly 23% over the past month and more than 60% over the last three months, keeping sentiment fragile.

SEI is currently trading near $0.124, consolidating inside a falling wedge on the daily chart. This pattern often forms late in downtrends, when selling pressure begins to fade and price compresses. SEI is holding just above the lower boundary of the wedge, making the next few sessions critical.

Momentum shows early signs of improvement. Between December 5 and December 14, price printed a lower low, while the RSI formed a higher low—a classic bullish divergence suggesting sellers may be losing control.

However, short-term risk remains elevated due to the token unlock on December 15, when 55.56 million SEI (around 1.08% of circulating supply) enters the market. Unlock events often increase near-term selling pressure, especially in cautious market conditions.

Key Levels to Watch

Bullish: A daily close above $0.159 would signal absorption of unlock supply and open a move toward $0.193 and higher.

Bearish: A drop toward $0.120 risks a breakdown toward the lower trendline, weakening the bullish divergence setup.

Bittensor (TAO)

Bittensor is approaching a major decision point as price compresses ahead of its upcoming halving. TAO is trading inside a symmetrical triangle on the daily chart, reflecting balance between buyers and sellers after weeks of downside pressure.

TAO is down about 15.5% over the past month and 6.6% over the past week, but declining volatility suggests a larger move may be approaching. This structure signals indecision rather than strong bearish dominance.

The halving is the key catalyst. By reducing token emissions, Bittensor tightens new supply. While halvings do not guarantee immediate upside, they often act as powerful catalysts when price is already compressed.

Key Levels to Watch

Bullish: A daily close above $301 would break triangle resistance, opening upside toward $321, and potentially $396 if momentum accelerates.

Bearish: Losing $277 weakens the structure and exposes $255, with $199 as a deeper downside risk if sentiment worsens.

Aster (ASTER)

Aster stands out due to a clear whale vs. retail battle heading into the third week of December.

On-chain data shows strong whale accumulation. Over the past seven days, whale-held ASTER balances surged by 42.7 million tokens, rising from approximately 39.85 million to 82.54 million ASTER—a 107% increase, signaling strong conviction from large holders.

At the same time, exchange balances increased by 10.48%, suggesting retail selling pressure even as whales accumulate. This conflict is reflected in the chart.

ASTER has been correcting since November 19 but is now compressing inside a triangle pattern, signaling indecision. A hidden bullish divergence has formed, where price made a higher low while the RSI printed a lower low—often a sign of selling exhaustion.

Key Levels to Watch

Bullish: A daily close above $0.94 would break triangle resistance, opening targets at $0.98, followed by a potential 16% move toward $1.08 if momentum and whale support persist.

Bearish: A break below $0.88 invalidates the bullish setup and exposes $0.81, shifting control back to sellers.

Final Takeaway

SEI, TAO, and ASTER are all approaching high-impact inflection points driven by supply events, technical compression, and on-chain behavior. While the broader market remains cautious, these setups could deliver sharp moves if momentum flips in the days ahead.
