A very critical signal has emerged in the altcoin market. Excluding the top 10 cryptocurrencies, the monthly MACD for the total altcoin market cap has flipped bullish for the first time in 19 months. What’s even crazier is that after similar signals appeared in the past: 2020 → Altcoin market cap exploded by +3,600% 2023–2024 → Subsequent peak gains were around +236% And now, the third signal for 2026 is forming. I don’t think history will repeat itself exactly, nor does it mean we’ll see another +3,600% this time. But a bullish flip on the monthly MACD isn’t about whether prices will rise tomorrow. What it truly tells you is this: The long-term momentum of the altcoin market is shifting from bearish to bullish. Over the past year, everyone’s been asking: “Will altcoin season ever come back?” Now, I’m starting to focus on a different question: If this really is the beginning of a new altcoin cycle, do you have enough chips in hand? BTC opens up liquidity. ETH takes the baton. And finally, funds flow into higher-beta altcoins. The truly insane market action might still be ahead.
