12 Charts to Understand the Downturn in September’s Crypto Market

·

The crypto market continued its sluggish performance in September, with many key indicators showing further declines. Despite hopes for a rebound following the corrections seen in August, the broader ecosystem remained under pressure. This article breaks down the state of the crypto market in September using 12 insightful charts and data points, revealing trends across on-chain activity, exchange volumes, miner revenues, derivatives markets, and more.

These insights are based on research by @lars0x and compiled for deeper analysis. Below is a comprehensive look at what shaped the market last month.

🔹 Decline in Major On-Chain Transaction Volumes

One of the clearest signs of reduced market activity was the drop in adjusted on-chain transaction value for both Bitcoin and Ethereum.

In September, the total adjusted on-chain transaction volume fell by 17.5%, reaching $145 billion. Bitcoin led the decline with a 20.83% drop, while Ethereum saw a slightly smaller but still significant 12.6% decrease.

This reflects weaker user engagement and fewer large-scale transfers, often an early indicator of bearish sentiment or reduced confidence in near-term price movements.

🔹 Stablecoin Activity Dips — But Supply Grows Slightly

Stablecoin transaction volume also declined, falling 10.7% to $465.2 billion in September. Lower stablecoin transfers typically suggest reduced trading activity or capital inflows into crypto markets.

However, there was one positive sign: the total stablecoin supply increased to $116 billion, marking a 0.75% growth — one of the few upward-trending metrics last month.

USDT maintained its dominance with a 72.3% market share, though this was a slight decrease from August. Meanwhile, USDC’s share dropped further to 20%, continuing its downward trend amid regulatory scrutiny and competition.

This subtle shift highlights growing user preference for non-custodial or less-regulated stablecoins during uncertain times.

🔹 Miner and Staking Revenues Continue to Shrink

Bitcoin miner revenue dropped to $753 million in September — a 6.4% decline — due to lower fees and reduced transaction volumes. With block rewards fixed until the next halving, miners are increasingly dependent on fee income, which remains under pressure.

Similarly, Ethereum staking rewards fell by 11.2%, dropping to approximately $115 million. This decline correlates with lower network usage and fewer validator incentives amid reduced DeFi activity.

These trends signal tightening economic conditions for network participants who rely on consistent usage to sustain profitability.

🔹 Ethereum Burns Over 44,000 ETH in September

Despite lower activity, Ethereum’s deflationary mechanism remained active. In September alone, 44,267 ETH (worth around $71.7 million) were burned through transaction fees under EIP-1559.

Since the implementation of EIP-1559 in August 2021, over 3.62 million ETH have been permanently removed from circulation — equivalent to about $10.24 billion at current valuations.

While burn rates slowed compared to previous bull cycles, this ongoing supply contraction supports long-term scarcity dynamics, especially if network demand recovers.

🔹 NFT Market Sees Sharp 31.8% Drop in Trading Volume

The Ethereum-based NFT market experienced a steep decline, with trading volume plunging 31.8% to just $261 million in September.

This reflects waning retail interest and fewer high-profile launches. However, one trend stands out: Blur has now surpassed OpenSea in monthly trading volume for eight consecutive months, signaling a shift in market leadership within the NFT space.

Although overall activity is down, platform competition remains fierce — suggesting innovation continues even during downturns.

🔹 CEX Spot Volumes Hit Lowest Level Since 2020

Centralized exchanges (CEX) saw spot trading volumes drop by 28.3%, falling to $187.7 billion — the lowest level since October 2020.

This dramatic contraction indicates reduced liquidity, fewer active traders, and limited new capital entering the market. Low spot volumes often precede extended consolidation phases unless catalyzed by macroeconomic or regulatory developments.

🔹 Exchange Market Share Shifts: Binance Drops, Others Hold Steady

Despite declining overall volume, exchange market shares remained relatively stable — though Binance saw a notable dip:

Binance’s decline may reflect increased regulatory scrutiny or users diversifying across platforms for risk management.

Coinbase and Kraken held their ground, likely benefiting from stronger compliance frameworks and institutional trust.

🔹 GBTC Trading Volume Nearly Halves

Grayscale’s Bitcoin Trust (GBTC) saw its daily average trading volume fall by 46.9%, dropping to just $36 million.

This sharp decline suggests waning investor interest in indirect Bitcoin exposure through traditional financial vehicles — possibly due to anticipation of upcoming spot Bitcoin ETF approvals in the U.S., which could render GBTC less attractive.

As regulatory clarity improves, legacy products like GBTC may continue losing relevance unless structural changes occur.

🔹 Futures Markets Show Mixed Signals

Derivatives markets presented a mixed picture:

Rising open interest suggests some traders are positioning for future volatility — potentially bullish if accompanied by price increases.

However, actual trading volumes told a different story:

This divergence implies that while positions are being built, overall speculative activity remains subdued.

🔹 CME Bitcoin Futures See Declines Across the Board

Even regulated futures markets felt the downturn. CME’s Bitcoin futures:

These drops indicate reduced institutional participation or hedging activity on traditional finance platforms — a concern for those hoping for FIAT-backed crypto adoption.

Lower CME volumes may also reflect traders moving to more liquid or leveraged venues like offshore exchanges.

🔹 Options Markets Contract Sharply

Both Bitcoin and Ethereum options markets contracted significantly in September:

Declining options activity signals reduced hedging demand and lower expectations for near-term volatility — often seen during periods of market apathy or uncertainty.

✅ Frequently Asked Questions (FAQ)

Q: Why did crypto markets remain weak in September?
A: A combination of low on-chain activity, declining exchange volumes, reduced miner/staker revenues, and shrinking derivatives markets contributed to sustained weakness. Macroeconomic factors like rising interest rates and strong U.S. dollar also played a role.

Q: Does rising stablecoin supply indicate future bullishness?
A: Not necessarily. While growing supply can suggest preparation for future inflows, current transaction volumes remain low — meaning new stablecoins aren’t being actively used yet. It could be early accumulation or offshore movement.

Q: Is Blur overtaking OpenSea a significant trend?
A: Yes. Blur’s dominance in volume reflects its focus on professional traders and incentive programs. However, OpenSea still leads in user base and NFT collections. The competition drives innovation but also raises concerns about wash trading.

Q: What does falling GBTC volume mean for Bitcoin ETFs?
A: Declining GBTC interest may signal investor anticipation of approved spot Bitcoin ETFs, which would offer lower fees and better liquidity than GBTC’s current structure.

Q: Can futures open interest rise while volume falls?
A: Yes. Rising open interest with falling volume suggests longer-term positioning rather than active trading — possibly indicating cautious optimism among derivatives traders.

Q: Are lower NFT volumes permanent?
A: Likely not. NFT markets are cyclical and tied closely to broader crypto sentiment and DeFi trends. A recovery in Ethereum activity or new use cases (e.g., gaming, identity) could reignite interest.
