Recent trends in Bitcoin ETF inflows have shown a significant increase in investor interest. Bitcoin spot ETFs experienced total net inflows of $48.74 million on 31 May, marking the 14th consecutive day of net inflows for these funds. This sustained investor interest in gaining exposure to Bitcoin through financial products available on the fiat markets indicates a growing appetite for the cryptocurrency among users who are not primarily from the crypto space.
However, the inflows were not evenly distributed across all Bitcoin spot ETFs. Grayscale's GBTC registered net outflows of $124 million, while BlackRock's IBIT and Fidelity's FBTC saw inflows of $169 million and $5.9047 million, respectively. This suggests that investors are shifting their preferences towards newer entrants in the Bitcoin spot ETF market.
The rising interest in BTC ETFs implies that Bitcoin could become even more mainstream, fueling greater adoption. While whale interest in BTC has grown significantly over the last few days, retail interest has declined, indicating that not all holders are equally optimistic. If retail investors continue to sell their holdings, it could exert downward pressure on BTC's price charts. Additionally, the state of miners, who may have to sell their holdings to remain profitable, could contribute to a surge in selling pressure on BTC.

The increase in whale interest in Bitcoin indicates that large investors and entities are accumulating Bitcoin, which can potentially drive the price of BTC higher in the future. This is because whales hold a significant amount of Bitcoin and their actions can influence market trends and liquidity. However, it is important to note that retail interest in BTC declined significantly during the same period, which could lead to downward pressure on BTC's price charts if retail investors continue to sell their holdings. Nonetheless, the overall trend of increasing whale interest in Bitcoin suggests a bullish outlook for the market.

The inflows and outflows among different Bitcoin spot ETFs have varied significantly. Grayscale's GBTC experienced significant outflows, exceeding $130 million2. In contrast, Fidelity's FBTC attracted $5.6 million, and Ark's ARKB drew $4.2 million in inflows. BlackRock's iShares Bitcoin Trust has accumulated over $17 billion in assets under management, driven by significant net inflows and substantial gains in digital asset prices this year. Since their launch, the 11 U.S.-based spot Bitcoin ETFs have attracted around $12 billion in total net inflows. However, there has been a slowdown in inflows since late March, indicating a potential shift in investor sentiment.
