3 Altcoins That Could Hit New All-Time Highs In The Third Week Of March 2026

As the crypto market enters the third week of March, several altcoins are showing technical signals that could position them for major price moves. With momentum building across parts of the altcoin market, a few smaller projects are drawing increased trader attention.

BeInCrypto has analysed three altcoins that could benefit from this momentum and form new all-time highs in March.

Adi (ADI)

ADI is trading less than 4% below its all-time high of $3.903, set just last Sunday. Few tokens are positioned this close to record levels in the current market environment. A confirmed breach of that ceiling would mark a significant technical milestone, signaling sustained bullish momentum for the altcoin.

A strengthening correlation with Bitcoin, currently at 0.65, is reinforcing ADI’s short-term bullish outlook. As BTC approaches the critical $75,000 mark, ADI stands to benefit directly from that momentum. A successful Bitcoin breakout could carry ADI past its $3.903 ATH and toward the $4.101 target.

Fading bullish momentum or a Bitcoin downturn poses the primary downside risk. A reversal in BTC’s trajectory would likely drag ADI lower, breaking through the $3.700 support level. Deeper losses would expose the altcoin to a decline toward $3.563, fully invalidating the current bullish thesis.

Cystic (CYS)

CYS is trading 38% below its all-time high of $0.600, set earlier last week. The altcoin is currently pressing against the $0.442 resistance level. Reclaiming lost ground from that peak requires a decisive technical breakthrough at this ceiling before any meaningful recovery trajectory can be established.

The $0.442 resistance aligns with the 61.8% Fibonacci retracement line, making it a technically critical flip zone. The Money Flow Index shows strengthening buying pressure among CYS holders, providing momentum for a potential breakout. Clearing $0.442 would open the path toward $0.482 and $0.532, bringing the ATH back within reach.

Failure to sustain bullish momentum would leave CYS trapped below $0.442. A reversal could drag the altcoin toward $0.387, with deeper selling extending losses to $0.352. A breakdown to that level would fully invalidate the current bullish thesis and signal a broader trend deterioration for the altcoin.

Siren (SIREN)

Another token amongst the altcoins nearing their all-time highs is SIREN, which posted a new ATH during today’s intraday session, reaching $0.697. The altcoin continues building on its recent upward momentum with consistent gains. This record-breaking price action signals strong and sustained investor demand, positioning SIREN as one of the more compelling performers in the current market cycle.

The 20-day exponential moving average is acting as a firm support level well below the current price, confirming a healthy bullish structure. This distance between price and EMA support indicates SIREN has room to extend its rally. The next upside target sits at $0.766, above which new all-time highs would continue forming.

Profit-taking by investors remains the primary reversal risk at these elevated levels. A shift toward selling could push SIREN down to $0.540, with deeper losses extending toward $0.470. A decline to that level would fully invalidate the current bullish thesis and signal a broader sentiment reversal for the altcoin.
