Bitcoin's gap with the rest of the cryptocurrency market has widened into a chasm. Over the past two years, Bitcoin gained 28% while the median mid-cap altcoin lost 74% — a median, meaning half of that cohort fell even further — and Ethereum landed roughly sideways, according to a new report from analytics firm Glassnode and crypto exchange Bybit. The figures capture a cycle in which holding almost anything other than Bitcoin has been a losing bet.

The report frames the divergence as the defining feature of this cycle: Bitcoin compounding steadily higher while the mid-cap complex, as the authors put it, "halves and halves again."

Ethereum, the second-largest cryptocurrency, ended the stretch with little net movement, underscoring how narrowly the gains have concentrated at the top of the market. It marks a stark reversal of the "altseason" pattern many holders came to expect, in which capital rotates from Bitcoin down into smaller tokens as a rally matures. The practical consequence for holders was stark: the same two-year window produced a 28% gain for Bitcoin and a roughly three-quarters loss for the typical mid-cap, making asset selection the dividing line for returns this cycle.

The same concentration shows up in how leverage is distributed across the market. Futures open interest — the total value of outstanding derivative contracts — is a standard gauge of leveraged positioning, and the report measures it against each asset's size. According to the report, Bitcoin carries futures open interest worth about 2% of its market capitalization, while speculative small caps carry far more, with PEPE near 24%. In other words, the froth has pooled in the market's riskiest corners even as its safest asset has done the heavy lifting on price.

The usual caveats apply. The report is a Glassnode and Bybit collaboration, with data as of the settled close of August 23, meaning the figures do not capture trading after that date, and Glassnode's venue coverage is limited, so the numbers describe the venues it tracks rather than the entire market.

Whether the rotation is turning is the live question. Just days ago, Bitcoin surged back above $80,000 after a dovish Federal Reserve forecast, and the rebound dragged the broader market with it, with the total crypto market capitalization up 4.6% in a day to about $2.85 trillion. Several majors outran Bitcoin in the bounce, with Solana up roughly 10% on the day and names like NEAR and Uniswap posting far larger gains, hinting at the kind of breadth that had been missing for a year. One strong session does not settle the question; follow-up readings on market breadth and fund flows will show whether it holds.

Institutional demand still tilts heavily toward the top. Spot ETFs wrap token exposure into a fund that trades on traditional exchanges, which makes their daily flow reports a public gauge of where that demand is heading. Spot Bitcoin ETFs have pulled in about $55.2 billion in cumulative net inflows, dwarfing the roughly $13.1 billion that has flowed into Ethereum funds, which recently logged a multi-day outflow streak. Solana's spot ETFs, newer and smaller, have drawn about $29.7 million.

The report's own framing captures why that matters: flow concentrates where performance concentrates. For now, both remain concentrated at the top of the market, and the next rounds of flow and breadth data will show whether that is starting to change.
