Bitcoin inflows in the past 24 hours (as of May 20-21, 2025):

* Inflows from Bitcoin Spot ETF in the US:

* Bitcoin Spot ETFs in the US recorded net inflows of 41.7 million USD just yesterday (May 20, 2025), marking the fifth consecutive day of inflows.

* In the past three weeks, these ETFs have attracted a total of 6.9 billion USD in new capital. This indicates strong and continuous demand from institutional investors.

* Exchange Netflows:

* Data from IntoTheBlock shows that net outflows are -631.04 million USD (negative 631.04 million USD). This negative figure means that the amount of Bitcoin withdrawn from exchanges is greater than the amount deposited.

* Significance: This is a signal often considered positive (bullish), indicating that investors are withdrawing Bitcoin from exchanges to hold long-term or transfer to cold wallets, reducing selling pressure.

* Bitcoin supply on exchanges:

* The amount of Bitcoin available on exchanges has decreased to only 7.1% of the total supply, the lowest level since November 2018. This reinforces the accumulation trend and holding Bitcoin long-term.

* Bitcoin Futures Open Interest:

* Bitcoin Futures Open Interest has reached a record high of 75.14 billion USD (as of May 21, 2025).

* Significance: This indicates that a large amount of capital is flowing into the derivatives market, reflecting strong bullish expectations and a willingness to use leverage to maximize profits.

* Stablecoin inflows:

* Although there is no specific figure for stablecoin inflows directly into Bitcoin in the past 24 hours, the stablecoin market in general is growing. The total market capitalization of stablecoins increased by 5 billion USD in April and continues to rise sharply (USDT and USDC increased by 2.5 billion USD and 1.2 billion USD respectively in the past week).

* Significance: The increase in stablecoin capitalization is often seen as a sign of new capital ready to flow into the cryptocurrency market, including Bitcoin.

Summary:

In the past 24 hours, Bitcoin has seen significant capital inflows from institutional ETF funds and the withdrawal of Bitcoin from exchanges, signaling strong accumulation sentiment. Although there is no overall single figure for 'how much has flowed in' (as the inflows come from various channels and complex interactions), key indicators show:

* About 41.7 million USD has flowed in through the ETF channel in just 24 hours.

* More than 631 million USD in Bitcoin has been withdrawn from exchanges, indicating a preference for holding rather than selling.

* The surge in open interest for futures contracts is also evidence that new capital and bullish expectations are being pumped into the market.

All these factors create a very optimistic picture for the Bitcoin market, with a goal of reaching new historical highs.
