A popular crypto analyst believes that altcoins are on the verge of experiencing a significant surge in the bull market. TechDev, a well-known analyst on the social media platform X, has alerted his 460,100 followers to a bearish reversal signal on the Bitcoin dominance (BTC.D) chart. The BTC.D index measures the proportion of the total crypto market cap that belongs to Bitcoin. A bearish BTC.D chart indicates that altcoins are poised to outperform Bitcoin. TechDev points out that the five-day chart shows a bearish divergence, suggesting that Bitcoin is losing momentum against altcoins. He predicts that this could lead to the largest drop in Bitcoin dominance in four years. TechDev, who follows Elliott Wave theory, states that altcoins are currently in the second wave of a bullish surge, and that the third wave, which is typically the longest wave, is yet to come. To support his view, TechDev presents an eight-week chart of the OTHERS index, which tracks the market capitalization of all cryptocurrencies excluding the ten largest digital assets and stablecoins. The chart indicates that OTHERS is retesting its exponential moving average (EMA) as support, a pattern that was observed in the early stages of the 2017 and 2020 bull markets. TechDev concludes by suggesting that altcoins are far from over and that investors will witness the third wave of their rally.
