In options, ETH OI has climbed to a YTD high ~$16.1B, alongside spot around $4.6k. Elevated open interest signals strong demand for optionality around the breakout.

Premiums confirm the tilt: call premium paid ~$82M (Aug 8) and still ~$31.5M (Aug 11), consistently outpacing puts. Traders are paying up for upside convexity as ETH presses higher.

In periods of heightened volatility, Glassnodeโ€™s Supply by Investor Behavior metric gives a deeper pulse of the market. For Bitcoin, we are seeing:

๐Ÿ”ธSupply held by First Buyers has risen +1.0% (4.88M โ†’ 4.93M BTC) over the past 5 days - showing fresh demand continues to enter.

๐Ÿ”ธConviction Buyers rose +10.1% (933K โ†’ 1.03M BTC) over 5 days. Yet compared to Aprilโ€™s surge, engagement looks muted - suggesting this dip is too shallow for strategic buying, or investors remain hesitant.

๐Ÿ”ธLoss Sellers spiked +37.8% (63K โ†’ 87K BTC) over the past 5 days. Still, compared to earlier this year, realized losses remain contained - suggesting few investors are panicking.

๐Ÿ”ธProfit Takers jumped +5.4% (1.73M โ†’ 1.83M BTC), the largest spike YTD. For some investors, this clearly has been a time to lock in gains and take chips off the table.

Fridayโ€™s BTC options saw a record ~$226M in premiums (~69% calls) as both sides repriced risk. By Monday it slumped to ~$18M with puts mostly sold ($5.5M received vs $0.37M paid) and calls ~flat - protection demand faded; market is leaning to stabilization/vol compression.

BTC options positioning has shifted higher: the net-premium heatmap shows a fresh cluster of net call buying in the $124kโ€“$130k strikes (+$41M cum.) while sub-spot put demand is light. After last weekโ€™s spike, positioning implies a 120โ€“130k magnet, not new downside hedging.

Last week, Bitcoin surged to a new ATH above $123k before retreating toward $114k. This weekโ€™s edition of BTC Market Pulse unpacks this slowdown: ETF demand remains strong, derivatives run hot, but on-chain signals point to fragility. Read it here: https://glassno.de/41c4VDB

The market is showing signs of contraction following significant profit-taking from investors holding for over 1 month (excluding daily traders).

Letโ€™s look at when and how much profit was realized (30D-EMA) across the top 5 assets:

Bitcoin (BTC)
On July 18, >1-month BTC holders realized over $1.5B in profit, marking the largest profit-taking spike since December 2024.

Ethereum (ETH)
On August 16, realized profit peaked at $575M, the largest profit-taking spike of this cycle so far. A clear sign of longer-term ETH holders taking risk off the table.

Solana (SOL)
On August 17, >1-month holders realized over $105Min profit, the biggest profit event since the early 2025 surge.

XRP
On July 24, profit-taking by longer-term holders spiked to $375M, suggesting strong distribution similar to December 2024 rally.

TRON (TRX)
August 6 saw a profit realization peak of $230M, highest in Tronโ€™s history, reflecting broader sell pressure across altcoins.

The Week On-Chain 33, 2025
Pressure continues to mount across the digital asset landscape, with broad-based sell-offs hitting major assets. Derivatives activity, in particular, continues to accelerate, leaving the market increasingly sensitive and reflexive in its structure.

Executive Summary
- Capital inflows into Bitcoin continue to decline, even as a new ATH of $124.4k forms, highlighting weaker investor demand.
- Altcoin open interest hit an ATH of $60B, but quickly fell by -$2.6B, marking the 10th largest drop on record.
- Ethereumโ€™s open interest dominance is at its 4th highest level, while perpetual futures volume dominance reached a new ATH of 67%.
- In prior cycles (2015โ€“2018, 2018โ€“2022), ATHs were reached 2โ€“3 months later than where we are in the current cycle.

The Anatomy of a Local Bottom

1- When the market enters a post-ATH contraction phase, short-term price action is often shaped by how top-buyers react to growing unrealized losses.

Right now, a dense cluster of supply, accumulated between $113k and $120k since early July, belongs to investors holding < 3 months.

2- To assess <3-month investor behavior, we use the SOPR by Age metric.

Currently, their SOPR is hovering around 0.96โ€“1.01, signaling mild loss realization. If pressure builds, local bottoms often form when this group capitulates, typically when SOPR drops below ~0.9.
