I just noticed that the inflow into U.S. Bitcoin ETF funds has increased again - on February 9th, it reached $144.9 million, marking the second consecutive quite positive day. This indicates that investors are still interested in what Bitcoin is and how to invest in Bitcoin through these regulated financial tools.

Looking into the details of each fund is quite interesting - Grayscale's Mini BTC leads with $130.5 million, while Ark Invest's ARKB and VanEck's HODL received $14.1 million and $12 million respectively. Other funds like Fidelity's FBTC also have positive cash flow, but BlackRock's IBIT withdrew $20.9 million. This clear dispersion shows that the Bitcoin ETF market is quite competitive.

The interesting part here is what the continuous inflow of money actually means - when funds receive new money, they have to buy Bitcoin from the open market, which creates buying pressure. With Bitcoin being what it is and how to invest in Bitcoin becoming more accessible through ETFs, traditional investors no longer need to worry about security or storage; just opening a regular brokerage account is enough to participate.

These two days also reflect a fairly stable market sentiment - money doesn't always flow in continuously, so when it does, it's usually a positive signal that investors are using these correction phases to accumulate more.
