3 Altcoins to Watch in the Last Week of May 2025

As May comes to an end, many crypto tokens are approaching significant developments. Altcoins are aiming to use these milestones as catalysts to push prices higher, following Bitcoin's recent upward momentum.

BeInCrypto has analyzed three altcoins for investors to watch as the second quarter draws to a close.

BNB

BNB price is predicted to surge soon, thanks to the upcoming Maxwell Hard Fork upgrade on Binance Smart Chain (BSC). This upgrade promises faster block times, improved network efficiency, and overall smoother performance, which could enhance investor confidence and platform usage.

The Maxwell Hard Fork could be the primary catalyst for increased chain activity. Currently, BNB is trading at $672, facing resistance levels at $686 and $700. A strong market reaction to the upgrade could narrow the 18% gap to BNB's All-Time-High (ATH) of $793.

However, if the Hard Fork is not warmly received, BNB may remain stuck below $686. This could invalidate the price increase prospects and slow the current momentum, as traders wait for clearer signs of sustainable growth.

Zilliqa (ZIL)

ZIL price has dropped 14.7% over the past two weeks, from $0.0149 to $0.0127. This decline may be due to delays in the Zilliqa 2.0 mainnet launch. However, any positive updates about the move could trigger a new price surge for the token.

Investors should monitor news about Zilliqa 2.0, as favorable developments could push ZIL to the resistance level at $0.0137. Breaking this level could restore price sentiment and signal potential recovery for this altcoin.

If ZIL fails to capitalize on the momentum, the price may fluctuate between $0.0125 and $0.0137. This sideways movement would weaken price increase prospects, indicating an uncertain period before the next significant move.

Optimism (OP)

OP price has recently been mostly sideways, but upcoming events could trigger a price surge. The unlocking of 31.34 million OP tokens this week, valued at $24.22 million, could boost prices as investors prepare for increased supply and activity.

Currently, OP is trading above the Ichimoku Cloud, showing price increase potential. This technical setup suggests OP could break the $0.80 resistance and continue climbing to $0.90, attracting more investor interest.

However, if it fails to surpass $0.80, the price increase prospects will be invalidated. In that case, the price could drop to $0.69 or lower, signaling potential weakness and requiring caution from traders.
