The crypto market remains cautious, but some tokens are facing important tests this week. As prices move sideways, attention is shifting toward three altcoins to watch in the third week of December. Each has a specific catalyst approaching, from supply changes to network events and shifting holder behavior.

These setups could drive sharp moves if buyers or sellers take control in the days ahead.

Sei (SEI)

SEI has been under steady pressure heading into mid-December, and price action reflects that caution. The token is down roughly 23% over the past month and more than 60% over the last three months, keeping sentiment fragile as the market looks for direction.

At the time of writing, SEI trades near $0.124, consolidating inside a broader falling wedge structure on the daily chart. This pattern often appears late in downtrends, where selling pressure slows, and the price begins to compress. For now, SEI is hovering just above the lower boundary of that structure, making the next few sessions critical. That tension qualifies SEI to be on the altcoins to watch list.

Momentum indicators offer a mixed but interesting signal. Between December 5 and December 14, the SEI price made a lower low, while the Relative Strength Index (RSI) formed a higher low. RSI measures momentum strength, and this bullish divergence suggests sellers may be losing control, even as price remains weak.

That said, near-term risk remains elevated due to SEI’s scheduled token unlock on December 15. Around 55.56 million SEI, roughly 1.08% of the circulating supply, is set to enter the market. Token unlocks often increase short-term selling pressure, especially when broader sentiment is cautious.

Key levels define the setup clearly. A clean move above $0.159 would signal that buyers are absorbing unlock-related supply and could open a rebound toward higher resistance zones. That includes $0.193 and even higher.

On the downside, a drop of roughly 3% from current levels, to $0.120, risks a breakdown toward the lower trendline. That would weaken the bullish divergence thesis.

Bittensor (TAO)

Bittensor price action has compressed into a tight range ahead of its upcoming halving, setting up a clear decision point. TAO has been trading inside a symmetrical triangle on the daily chart, showing balance between buyers and sellers after weeks of downside pressure. That kind of buyer-seller tussle makes it one of the top altcoins to watch in the third week of December.

TAO is down around 15.5% over the past month and roughly 6.6% over the last seven days. Short-term weakness continues, but volatility has dropped, which often appears before larger moves. This structure reflects indecision rather than outright bearish control.

The halving acts as the key backdrop. Bittensor’s halving reduces token emissions, tightening new supply. Historically, such events do not guarantee immediate upside, but they often act as a catalyst when the price is already compressed.

From a technical view, the first bullish trigger sits near $301. A daily close above this level would break the upper trendline of the triangle and signal renewed strength. That move opens a path toward $321, followed by $396 if momentum builds and broader market conditions cooperate.

Downside risk remains. $277 is critical support. A breakdown below it weakens the structure and exposes $255, with $199 as a deeper risk zone if sentiment deteriorates.

Aster (ASTER)

Aster stands out as one of the altcoins to watch in the third week of December because of a clear tug-of-war between whales and the broader market.

On-chain data shows aggressive whale accumulation heading into this week. Over the past seven days, whale-held ASTER balances jumped by about 42.7 million tokens, rising from roughly 39.85 million to 82.54 million ASTER. That is a 107% increase, signaling strong conviction from large holders ahead of the third week of December.

At the same time, exchanges tell a different story. Exchange balances took a 10.48% jump. This suggests possible retail selling even as whales accumulate.

That buyer-seller conflict is also visible on the chart. ASTER has been correcting since November 19 but is now compressing inside a triangle pattern, reflecting indecision. During this phase, a hidden bullish divergence has formed. Between November 3 and December 14, the price made a higher low while the Relative Strength Index (RSI) made a lower low, which often signals exhausting selling pressure.

That’s often associated with price rebounds. If this setup plays out, the first level to watch is $0.94. A daily close above it would break the triangle resistance and open the path toward $0.98, followed by a potential 16% move to $1.08 if momentum builds and whale support persists.

On the downside, losing $0.88 would invalidate the bullish divergence and expose $0.81, shifting control back to sellers.

XRP is trading near $1.99, down about 1% over the past 24 hours. Despite broader market volatility, it is only around 4% lower on the week, showing relative stability compared to many altcoins like ADA and BCH.

More importantly, the chart is flashing an early bullish reversal signal. The setup is not confirmed yet, but if one key level continues to hold, the odds of a short-term rebound, at least 9%, increase meaningfully.

Bullish Divergence Appears as the XRP Price Defends Key Support

XRP has formed a bullish divergence on the daily chart between December 1 and December 14. A bullish divergence happens when the price makes a lower low, but the Relative Strength Index (RSI) makes a higher low. RSI is a momentum indicator that measures buying and selling strength. When RSI improves while price weakens, it often signals that selling pressure is fading.

On the daily chart, a standard bullish divergence like this can lead to trend reversal — from bearish to bullish.

Yet, this divergence alone is not enough. It only matters if the XRP price holds support.

That support sits near $1.97. XRP has repeatedly defended this zone, and on-chain data helps explain why.

The cost basis heatmap shows a dense cluster of XRP bought between roughly $1.97 and $1.98.

Around 1.79 billion XRP were accumulated in this range. A cost basis heatmap shows where large groups of holders bought their coins. When price trades near these levels, holders are less likely to sell at a loss, which strengthens support.

As long as XRP stays above $1.97, the bullish divergence theory remains valid, provided the RSI reading stays strong.

Why $2.17 Is the First Real Test for the Bulls

If support holds, XRP has room to move higher. The first upside target sits near $2.17, which is roughly a 9% move from current levels.

This level matters because the cost basis heatmap shows heavy supply between $2.16 and $2.17. About 1.36 billion XRP were acquired in this zone. That makes it a strong resistance area, where selling pressure is likely to appear.

If the XRP price pushes through $2.17 with a daily candle close, it could open the path toward $2.28, then $2.69, and eventually $3.10. Yet, those levels remain secondary for now and depend on broader market conditions.

The invalidation is clear. A daily close below $1.97 would weaken the reversal setup and expose downside toward $1.81 and $1.77.

For now, the XRP price sits at a decision point. The bullish reversal signal is active, but only if the most important support level continues to hold.
