Bitcoin's Spot-Backed Rally Hides an Altcoin Leverage Trap Last Seen in 2025

Altcoin perpetual futures carried more open interest than Bitcoins on September 6, the first such flip since December 2024, according to Coinalyze data. That crossover comes even as Bitcoins own rally stays anchored in spot demand, not altcoin leverage. Neoclassic Capital Co-Founder and Managing Partner Michael Bucella called Bitcoins advance a healthy rotation. He said the initial surge came from short covering. Spot demand and rising call-option skew have since taken over as futures positioning eased. Altcoin Leverage Nears Levels Last Seen Before 2025s Crash Zcash drove most of the shift. ZECs derivatives book swelled to an all-time high near $2.4 billion during Zcashs decade-high rally. Short sellers absorbed roughly $34 million in forced closures as the token broke higher. Zcashs rally has drawn extra attention as Grayscale files to convert its ZEC trust into a spot ETF. That filing adds a new demand angle even as leverage climbs. Zcash is up almost 150% in a month.

Traders are rotating leverage further down the risk stack as Bitcoins rally matures. Proceed to Altcoins with Caution Bucella told CNBCs Halftime Report the buildup echoes conditions from October 2025. That was just before a sharp market-wide liquidation. He argued Bitcoins own move looks comparatively healthy. It is driven by spot buying rather than pure short covering. Im not saying that this move isnt sustainable. Im just saying you should proceed with a lot of caution. Michael Bucella, CNBC Bitcoins ETF-backed bid has held up despite a brief late-August outflow streak, per BeInCryptos September warning signs. Whether altcoin leverage unwinds as calmly is the open question for the rest of September.
