Top Altcoins to Watch This Week: Can ONDO and SUI Trigger a Breakout Rally?

While Bitcoin consolidates and many investors are unsure of the next move, a few altcoins are showing renewed momentum. Among them, ONDO and SUI have emerged with fresh gains after a quiet pullback in the previous week. Both of these coins observed a surge on Monday, and it was nearly 5 per cent. This positioned them for a possible breakout as these gains are not driven by hype but supported by reliable technical indicators, such as the MACD and RSI, which suggest growing bullish pressure.

In a market that is often driven by speculation, identifying reliable altcoins to watch is crucial for capturing early gains. ONDO and SUI are approaching major resistance levels, and a confirmed breakout could lead to double-digit percentage increases in the short term. The recent price movements, combined with positive momentum indicators, point to a possible rally for both tokens. Traders and investors should keep a close eye on these altcoins, especially as the broader crypto sentiment slowly turns more optimistic.

ONDO Bulls Take Charge as $1.02 Resistance Comes into View

Over the past several trading days, ONDO has shown signs of strength after finding support on a previously broken descending trendline. This trendline, which has capped prices since mid-December, now serves as a strong foundation for bullish movement. ONDO climbed 4.6 per cent between Wednesday and Saturday, dipped slightly on Sunday, and began Monday trading nearly 5 per cent higher around the $0.87 level.

The next key milestone is the 50-day Exponential Moving Average, currently sitting at $0.89. A daily close above this line would confirm short-term bullish strength and could trigger a move toward $1.02, which aligns with the 200-day EMA. According to the latest ONDO price prediction, a break above this level could push the asset even higher, potentially retesting the March 6 high near $1.20. This move would represent a 38 per cent upside from the current price.

SUI Eyes 30 Per Cent Rally if $2.34 Resistance is Broken

SUI has also shown promising signs after a sharp rejection earlier this month. The token faced resistance near its descending trendline on April 13 and dropped over 10 per cent through the weekend. However, a strong 5 per cent rebound on Monday pushed SUI back above the trendline, and it currently trades around $2.22, showing fresh potential for a breakout.

For the uptrend to continue, SUI needs to close above its key weekly resistance level of $2.34. If that occurs, the token could rally as much as 30 per cent toward the next resistance at $2.90. This level not only marks a technical target but also serves as a psychological barrier that could attract even more buyers. Based on current SUI price analysis, such a breakout would likely signal the start of a stronger bullish phase.

Technical indicators add further support to the bullish case. The MACD has already shown a bullish crossover, and the RSI is at 50 and pointing upward, suggesting that bearish pressure is fading. For continued upward momentum, RSI must push clearly above 50 and hold strong. If the price faces rejection at $2.34, however, it could drop back toward its April 7 low of $1.71, wiping out recent gains.

Traders looking for high-reward setups may find SUI to be an attractive candidate. Its price action and chart structure indicate that it is one of the more promising altcoins to watch this week.

Breakouts or Corrections Ahead for ONDO and SUI?

ONDO and SUI have emerged as two of the most compelling altcoins to watch this week. Both are nearing important resistance levels and show strong momentum based on MACD and RSI signals. With ONDO aiming to reclaim the $1.02 zone and SUI targeting a $2.90 breakout, the technical setups are favoring the bulls.

These price levels will be critical in determining the short-term direction. A successful breakout could open the door to more gains, while a failed attempt might invite pullbacks. Still, among a sea of uncertain altcoins, ONDO and SUI are shining bright. Whether you are an active trader or a long-term investor, these assets are well worth monitoring in the days ahead.
