Why Holding Anything But Bitcoin Has Been a Losing Bet for Two Years

A joint report from on-chain analytics firm Glassnode and crypto exchange Bybit characterizes the past two years as a cycle in which Bitcoin materially outperformed the broader crypto market. Using data through the settled close of August 23, the study shows Bitcoin up roughly 28% while the median mid-cap altcoin declined about 74%; Ethereum, by contrast, ended the period essentially sideways. The authors describe the pattern as a reversal of the usual ‘‘altseason’’ dynamic, with gains focused at the top rather than rotating down the market cap scale. The report also documents where leverage and speculative positioning accumulated. Bitcoin’s futures open interest equates to roughly 2% of its market capitalization on the venues Glassnode tracks, whereas certain small-cap tokens carry substantially higher relative futures exposure — PEPE is cited near 24%. That discrepancy suggests speculative froth has pooled in smaller, riskier assets even as Bitcoin supplied most of the market’s price appreciation. Flows into spot exchange-traded products mirror this concentration. Spot Bitcoin ETFs have amassed about $55.2 billion in cumulative net inflows, while Ethereum funds have drawn about $13.1 billion. Newly launched and much smaller Solana spot ETFs have attracted about $29.7 million. The report notes that capital flows tend to concentrate where performance has been strongest. Market dynamics were still in flux at the time of the report. A recent dovish projection from the U.S. Federal Reserve coincided with Bitcoin moving back above $80,000, a rebound that lifted broader market capitalization by 4.6% in a day to roughly $2.85 trillion. Some large-cap and mid-cap tokens outperformed Bitcoin during that bounce — Solana rose about 10% on the day, and names including NEAR and Uniswap posted larger gains — suggesting episodes of renewed breadth, though the report cautions its venue coverage is limited to the data Glassnode tracks.
