Week On-Chain, Week 29, 2025

Altcoins are showing broad strength following Bitcoin’s lead, but surging open interest across the sector suggests speculative froth may be building, raising the risk of sharper volatility ahead.

Executive Summary

- Bitcoin’s Realized Cap has hit $1T for the first time, marking a major milestone and reflecting BTC’s deep liquidity and rising significance in global macro markets.

- Altcoins are broadly outperforming Bitcoin, with Ethereum leading the charge. The Altcoin Market Cap has grown by over $216B in just the last two weeks.

- Open Interest in top altcoins has surged from $26B to $44B in July, signaling elevated leverage, which may fuel more intense and reflexive price swings.

- Ethereum has broken above key on-chain resistance levels, including the Active Investor Price and True Market Mean, but heavy sell pressure is expected around the $4.5k mark.
