Why does Bitcoin frequently decline around 18:00 Moscow time

Bitcoin almost every day drops at the same time—when the US market opens, activity and trading volume sharply increase.
The decline resembles the operations of large high-frequency traders who profit by pushing prices down and then buying at lower prices.
Jane Street is often mentioned in discussions due to its substantial holdings in Bitcoin ETFs and its resources to execute such operations, although there is no direct evidence of its involvement.
In recent weeks, many have noticed a strange pattern: Bitcoin often begins to decline when the US market opens—around 10:00 AM New York time(≈6:00 PM Moscow time). Sometimes, this is particularly pronounced: hours of gains vanish in just 15–20 minutes.

This situation also occurred during a recent trading session: Bitcoin lost 16 hours of gains within just a few minutes after US trading began. BeInCrypto's editorial team learned that there's a “fainting” of Bitcoin in the morning behind this.

Why does Bitcoin decline at the same time
When the US market opens, a large volume of trades occurs—participants start actively buying and selling assets. Liquidity sharply increases, making prices more sensitive to large-scale operations. During these moments, large traders can execute massive trades with almost no delay.

If a major participant dumps a large amount of Bitcoin into the market, prices will instantly fall. Then, as activity decreases, the market gradually recovers some of the decline.
What does this have to do with Jane Street
In the crypto community, it is believed that the morning synchronized decline is similar to the operations of high-frequency trading firms. These companies use algorithms capable of executing large numbers of trades within seconds, profiting from tiny price fluctuations.

One highly scrutinized company is Jane Street. In terms of size, it is one of the largest traders worldwide. The algorithms it employs operate at high speeds and handle large trading volumes. With these capabilities, large participants can influence asset prices in a short period, especially when there are大量交易在前几分钟内发生。

Currently, there is no direct evidence that Jane Street is involved in Bitcoin declines. However, it is often mentioned because, according to public information, it holds about $2.5 billion in BlackRock IBIT Bitcoin ETF. This indicates that the company has the resources to execute large-scale operations.

How to profit from it
Understanding its mechanism only requires imagining a possible algorithm:

At 10:00 AM New York time—when activity is at its peak—大量比特币被卖出。
Prices instantly drop because the market cannot process such a large volume of trades in time.
Subsequently, the same participant can buy Bitcoin at a lower price.
Profit comes from the difference between the selling price and the subsequent buying price.
This cycle repeats daily.
This method can profit from short-term intense volatility without aiming to long-term crush the market.
