Top 3 Meme Coins to Watch This Week as BUILDon Targets $0.60 Breakout

The top 3 meme coins on the weekly radar split into very different technical paths. BUILDon (B) extends a breakout, MemeCore (M) loses key support, and Siren (SIREN) coils below a descending trendline that has capped price since March. Daily charts show BUILDon pressing the 0.618 Fibonacci level at $0.48, MemeCore correcting toward $3.27 after rejection near $4, and SIREN testing the 0.786 Fibonacci retracement at $1.07 with expanding volatility. BUILDon (B) Bulls Press the $0.48 Resistance for a Third Time BUILDon trades close to $0.4679 after a 14.91% daily gain, with intraday highs near $0.52 and lows at $0.38. The coin spent months inside a wide accumulation zone between $0.09 and $0.30 that reached back to September 2025. Price broke out of that range on May 1 and confirmed the 0.382 Fibonacci retracement at $0.32 as fresh support. However, the 0.618 level at $0.48 has rejected B on three separate attempts so far in May. B daily chart / Source: Tradingview The Relative Strength Index (RSI) sits close to 70, deep inside bullish territory. Meanwhile, the Moving Average Convergence Divergence (MACD) prints another taller green histogram bar after a short pause, which signals renewed upside momentum. A confirmed daily close above $0.48 would open a path toward the 0.786 Fibonacci level near $0.60. Failure to clear that resistance could send the price back toward the $0.32 support shelf. MemeCore (M) Slides Back After Losing Curved Support In contrast to BUILDon, MemeCore trades at $3.27 after a 1.24% daily drop and shows clear technical weakness. The price action lost its exponential support curve at the end of April, which ended a steady advance that had held since February 1. After that breakdown, M corrected to the 0.618 Fibonacci retracement at $2.59 before bouncing higher. The recovery retested the broken curve as resistance on May 7, then stalled around $4 at the 0.236 Fibonacci level. M daily chart / Source: Tradingview The MACD now prints taller red histogram bars, which point to expanding bearish momentum. The RSI hovers in the neutral zone but trends lower, which warns that selling pressure has not yet been absorbed. A second visit to $2.59 remains the base case if the current pullback continues. On the upside, bulls would need to reclaim $4 to invalidate the bearish setup, with the prior high near $4.85 the next major hurdle. Siren (SIREN) Coils Under the Trendline as Volatility Returns Siren offers a different setup again, with price compressing under a descending trendline that goes back to March 23. The line was confirmed as resistance on April 17 and tested once more on May 9. SIREN currently trades at $1.17, close to the 0.786 Fibonacci retracement at $1.07, which has acted as a near-term magnet. Volatility, measured by the Bollinger Band Width Percentile (BBWP), recently sat at very low readings consistent with a contraction phase. SIREN daily chart / Source: Tradingview However, from May 6 through May 8, price activity began to expand again, with volatility ticking higher even though readings have not yet reached extreme zones. The RSI sits near 60 and slopes upward, which reinforces the building momentum. A breakout above the trendline would extend gains toward the 0.618 Fibonacci retracement at $1.85 and then $2.40. The long-term support sits near $0.75, and a daily loss of $1.07 would put that floor back in play.
