- The OTHERS to BTC index touched the lower channel again just like it did in 2017 and in 2020.
- Traders now look at the same setup that led to gains of over 11M BTC in past bull market cycles.
- Bitcoin dominance remains high but capital may shift if this chart pattern triggers another strong rebound.
A recent TradingView chart shared by @BitcoinSensus suggests that altcoins may be coiling for one of their strongest rebounds yet. The analysis compares the OTHERS/BTC index—tracking altcoin performance against Bitcoin—revealing a cyclical bottom forming near a historical trendline. The post, published July 6, 2025, stated that “Altcoins are coiling up for the biggest comeback ever,” and the data appears to support that claim.
The weekly logarithmic chart outlines a clear ascending channel dating back to 2015, with three cycle bottoms—2017, 2020, and 2025—touching the support line. The current value stands at 2.18M BTC, with historical rebounds pushing above 13M BTC in prior cycles. If the pattern repeats, the implied move could be over 6x from the current position.
Market participants are now watching closely to determine whether altcoins will replicate past rallies or diverge under current macro conditions.
Historical Chart Patterns Mirror Current Altcoin Setup
The OTHERS/BTC index reflects the combined market capitalization of altcoins relative to Bitcoin, offering insight into altcoin dominance cycles. The chart highlights three notable cycle lows, each aligning with the lower boundary of an established channel. Previous bounce points—2017, 2020, and now 2025—share structural alignment and relative timing.
In 2017, altcoins surged after bottoming around 0.3M BTC, peaking above 5.8M BTC by early 2018. A similar setup unfolded in 2021, following a bottom near 1.1M BTC, with a sharp rally above 11M BTC. The 2025 pattern now echoes those moves, following a decline that touched the ascending base line for a third time.
The chart’s upper trendline projects a potential resistance zone near 16M BTC by late 2027 or early 2028. This suggests significant upside remains if historical behavior holds, and investors are noting the symmetry.
Social Sentiment Confirms Anticipation for Major Altcoin Rebound
The tweet containing the analysis received over 28.9K views and triggered substantial discussion in the crypto community. Traders and influencers reacted to the post with optimism, indicating renewed confidence in a market rebound. Many pointed to the timing aligning with previous multi-year breakouts, suggesting a broader altseason may be approaching.
Comments under the tweet asked which altcoins are best positioned for the rebound, while others cited 2025 as a key reset year. The enthusiasm is further confirmed by the chart’s viral spread, reaching analysts and content creators across X (formerly Twitter).
Price action, volume build-up, and consolidation patterns among various altcoins also support the thesis. Many tokens have recently formed long-term bases and are now exhibiting breakout signs above key moving averages.
The Core Question: Can Altcoins Outperform Bitcoin Again in 2025?
Altcoins tend to outperform Bitcoin during market expansion phases, especially when Bitcoin’s dominance wanes. The current BTC dominance stands high, but a breakdown could redirect capital into smaller-cap tokens.
Several metrics now point to rising altcoin strength, including weekly momentum indicators and decreasing BTC dominance divergence. While Bitcoin remains the benchmark, traders are shifting focus toward emerging Layer 1s, gaming tokens, and DeFi protocols.
If history repeats, altcoins could lead the next wave of crypto growth by early 2026. But uncertainty remains around regulation, interest rates, and institutional behavior. The question now is whether altcoins will truly reclaim dominance or face fresh resistance in a changed market.
