On Tuesday some 48,000 bitcoins moved off Coinbase Pro, a favored exchange among institutional investors, according to data provider CryptoQuant.

The outflow was the biggest among crypto exchanges since crypto’s big crash in June of this year and the second-largest of all time. Exchange outflows suggest investors are withdrawing their crypto from exchanges and shifting from selling mode to accumulating mode.

The value of the crypto moved Tuesday totaled about $940 million and the transactions were partially split into batches of 122 bitcoins, which is a familiar pattern that came to fruition several times in the 2021 bull run, according to Maarten Regterschot, a CryptoQuant contributing analyst.

He also said the transactions were likely done in over-the-counter trading desks, and therefore might not affect the price of bitcoin.

Bitcoin was traded 1.5% lower Tuesday at $19,233.71. Ether was down 1.7% to $1,301.46. Both have been trading steadily sideways for about a month.

Meanwhile, while bitcoin’s correlation with stocks has fallen from its all-time high last month, it remains at historic highs and its price is still largely driven by macro triggers points, like key economic data reports and central bank policy. Its uncharacteristically low volatility, however, has been top of mind for the crypto market in recent days.

“Bitcoin has failed to make any significant moves since early June, with prices bouncing between an increasingly narrow range,” said Kaiko’s director of research, Clara Medalie. “Considering bitcoin’s current low price levels, trade volumes have remained relatively resilient since last year’s all-time highs. There is no discernable decrease in volumes since September despite the increasingly low volatility.”

Elsewhere, the major stock indexes were making solid up moves on Tuesday morning. Crypto equities were mostly in the green with the exception of “crypto bank” Silvergate, whose earnings amid the recent apathy in crypto came in weaker-than-expected Tuesday, according to FactSet.
