Crypto analyst Astronomer (@astronomer_zero) says his long-standing bottom thesis on the ETH/BTC pair has played out and published explicit cycle targets anchored to the cross. In a chart shared on X, he reiterated that “ETH bottom call” is in and framed the roadmap entirely through ETH/BTC levels rather than ETH/USD, arguing that Ether’s outperformance typically follows Bitcoin’s impulse and that “all major liquidity comes from BTC.”
Astronomer’s post centers on a multi-month “zone” on ETH/BTC that he had marked in advance as a potential cyclical inflection. He writes that the call looked “delusional” when first drawn—“a ‘ridiculously long’ prediction line (straight up from the bottom) from what ‘could impossibly be the ETHBTC bottom’ at the time”—but says the turn aligns with his proprietary sentiment work.
With that backdrop, the chart and commentary lay out three ETH/BTC targets for the remainder of the cycle. The first is 0.058 BTC per ETH, which he notes was “still 35% above here” at the time of posting and, translated directly using spot Bitcoin, “puts ETH at approx. $6.500 if BTC stays at this price.”
The second is 0.091, “pretty much a double from here,” corresponding to “$ETH to $10,000+, 5 figures,” a level where he says he “will have sold over half of my spot bags.”
The final and highest target is 0.16, “just under a 4x from here, putting ETH at $20,000 or higher.” He is explicit that the 0.16 mark is aspirational rather than base case: “That is certainly my highest target, and I do not expect that to be reached guaranteed. But I love it open just in case it does happen.”
The technical logic he presents is deliberately pair-driven. By mapping the cycle with ETH/BTC, he seeks to capture relative strength rather than absolute price and to sidestep the moving base of BTC’s dollar value. The implied ETH/USD levels in his post are simple translations of ratio × BTC price; he adds that those USD conversions “will, in fact, be underestimates as I also see BTC rise further.” In other words, the chart’s horizontal levels are ETH/BTC at 0.058, 0.091, and 0.16; the USD numbers are contingent and will float with Bitcoin.
Importantly, the pathway he describes is conditional on the same relative-rotation dynamic that has governed past cycles: Bitcoin leads, Ether lags until liquidity rotates, then ETH/BTC advances through predefined shelves. In that framework, the analysis does not depend on any single ETH/USD number; it depends on ETH/BTC reclaiming and holding the cited bands.
At press time, ETH traded at $4,621.
