Bitcoin Spread Oscillator Signals Growing Altcoin Momentum – Altseason Entry Signal?

Bitcoin is trading at critical levels as the entire crypto market enters a high-volatility phase fueled by renewed optimism and strong momentum. After weeks of bullish price action, BTC has consolidated above $103K, setting the stage for a definitive move. Market participants are closely watching whether Bitcoin will break above all-time highs or face another rejection—either scenario could trigger significant ripple effects across the altcoin space.Analysts are increasingly pointing to signs of an incoming altseason, where capital rotates from Bitcoin into alternative cryptocurrencies. According to recent insights from CryptoQuant, the Bitcoin Market Performance & Altcoin Spread value is now at 38%. This proprietary metric gauges relative performance and momentum across major assets like ETH and SOL compared to BTC. A reading above 50% is historically viewed as confirmation that an altseason has begun. With just 12 percentage points remaining, sentiment is heating up across the market.This key transition phase could define the market’s direction over the coming weeks. If Bitcoin holds its gains and altcoins continue to outperform, it would mark a powerful shift in capital allocation—one that could set the tone for the rest of the cycle. For now, all eyes are on the 50% mark.Altcoin Oscillator Signals Building Momentum As Bitcoin Approaches ATHBitcoin has gained over 12% in the past week and more than 40% since its April 9th low, confirming a sustained five-week uptrend that reflects growing investor confidence. This rally marks a key shift in market sentiment after months of volatility and uncertainty. With BTC now trading just below its all-time high near $109K, bulls are in control—but the real test lies ahead.The coming weeks are expected to be decisive. Some analysts anticipate a clean breakout above the previous high, which would confirm a continuation of the broader bull cycle. Others argue that current levels may trigger profit-taking and a potential short-term correction. Either way, momentum remains strong, and Bitcoin’s ability to hold above $100K will be crucial.At the same time, market dynamics are shifting. Top analyst Axel Adler points to the Bitcoin Market Performance & Altcoin Spread indicator—a composite oscillator that tracks how altcoins like Ethereum and Solana perform relative to BTC. According to Adler, this metric recently hit 38%. Historically, once the 30-day moving average of the oscillator crosses 50%, it signals the beginning of an altseason.With just 12 percentage points remaining before the signal confirms, capital rotation from Bitcoin to altcoins could be imminent. Green dots on the oscillator indicate these historical inflection points. If this trend continues and altcoins begin to outperform, it would confirm a broader risk-on environment across crypto.BTC Weekly Chart Analysis: Resistance Holds for NowThe weekly chart for Bitcoin shows that the price is currently consolidating just below the all-time high zone after failing to break cleanly above it. BTC reached a high of $105,706 before pulling back and closing the weekly candle around $103,850. This level marks a critical resistance area, historically significant from January’s peak, and now acting as a short-term ceiling for bullish continuation.Despite the rejection from highs, the structure remains bullish. BTC is holding well above the psychological $100,000 level and key moving averages. The 200-week SMA sits far below at $47,375, and the 200-week EMA at $52,457, both indicating a strong long-term uptrend is intact.Volume over recent weeks confirms rising participation, supporting the idea of growing interest as Bitcoin approaches price discovery once again. The key now is whether bulls can reclaim the $105K level on a weekly closing basis, which would open the door for a breakout toward $109K and beyond.If the price fails to hold above $100K in the coming sessions, a deeper retrace could test lower support zones around $96K–$94K. Still, the momentum is bullish, and the weekly close above $103K keeps the rally alive.Featured image from Dall-E, chart from TradingView
