Bitcoin and Ether Fell to Late-July Lows as the Crypto Selloff Widened

Bitcoin and ether fell to their lowest levels since late July during the September 8, 2020 UTC trading session, extending a selloff that had spread across major cryptocurrencies and decentralized-finance tokens.

Kraken’s market report placed bitcoin, which the exchange designated XBT, at $10,118 at the end of its reporting day, down 2.5%. Ether finished at $337, down 4.8%. The exchange recorded $291.2 million of trading across its markets, including $147.3 million attributed to XBT and $61.1 million to ETH.

The move mattered because it interrupted a summer advance that had lifted both leading assets and generated intense demand for newer protocol tokens. September 8 demonstrated that the same market could reverse broadly: bitcoin declined, ether fell faster, and several assets associated with the expanding decentralized-finance trade suffered still larger losses.

What the September 8 data showed

Kraken reported chainlink at $11.728, down 6.5%, and polkadot at $4.2713, down 7.2% over the UTC session. By comparison, bitcoin’s 2.5% loss was smaller but still consequential because it left the largest crypto asset close to the psychologically prominent $10,000 level.

CoinMarketCap’s September 8 historical snapshot independently recorded bitcoin at $10,131.52, down 2.25% over its preceding 24-hour window. Ether stood at $337.60, down 4.21%; chainlink was $11.79, down 5.79%; and polkadot was $4.2743, down 6.50%.

The small differences between the two records are expected. Kraken measured activity on its own markets from 00:00 through 23:59 UTC. CoinMarketCap aggregated covered venues using a separate snapshot methodology and did not state a precise cutoff time on the historical page. Cryptocurrency has no consolidated closing auction, so neither dataset represents a universal market close.

CoinMarketCap’s seven-day measurements showed how far the correction had progressed by September 8: bitcoin was down 15.24%, ether 29.22%, chainlink 26.89% and polkadot 32.25%. Those are provider-calculated changes from one historical snapshot, not returns available to every trader or proof that the assets moved for the same reason.

No single catalyst was established

Contemporaneous analysis from digital-asset investment firm Arca described four consecutive selling days through the U.S. Labor Day period and calculated, using third-party market data through September 6, a 12.4% weekly bitcoin loss and a 16.6% decline in the Bloomberg Galaxy Crypto Index. Arca said it could not identify a clear fundamental catalyst for the initial decline.

That assessment is useful context but remains analysis, not a verified causal finding. Arca discussed possible miner selling, leverage and the market’s limited capacity to absorb concentrated supply. The cited records do not establish which participants sold on September 8, how much leverage was forcibly closed, or whether equity-market weakness directly caused cryptocurrency prices to fall.

The more defensible interpretation is structural. Ether’s Kraken decline exceeded bitcoin’s by 2.3 percentage points, a Coinburn calculation from the exchange’s rounded returns. LINK and DOT fell faster still. That pattern was consistent with traders reducing exposure more aggressively in assets that had participated strongly in the summer’s protocol-token rally, but price data alone cannot establish investor motives.

Why the session mattered

September 8 exposed the difference between growing activity and market resilience. Kraken still processed hundreds of millions of dollars in trading, while the broad decline showed that liquidity and participation did not prevent sharp, synchronized losses.

The event-day record supports a limited conclusion: bitcoin and ether reached their lowest Kraken levels since late July, major protocol tokens underperformed bitcoin, and independent aggregated data confirmed the direction and approximate magnitude of the decline. It does not establish a universal closing price, a definitive cause, realized investor losses or what prices would do after September 8.
