Citi analysts have stated that the recent sale of Bitcoin holdings by Strategy (MSTR) is less significant than the broader issue of a lack of new investors entering the Bitcoin market. The sale was part of a tax-optimization strategy and does not alter the company's long-term plans. According to Citi, the flows from spot Bitcoin exchange-traded funds (ETFs) account for approximately 45% of weekly price movements, making them a critical indicator of investor interest. However, recent trends show negative ETF flows, coupled with a diminishing likelihood of a U.S. crypto market structure bill passing this year, which could further dampen investor sentiment. The report highlights that while Strategy's sale has raised concerns about potential selling from major corporate backers of Bitcoin, the primary driver of Bitcoin's price remains ETF flows, not treasury-related selling. As Bitcoin trades around $67,200, the outlook for fresh investor inflows appears bleak without regulatory advancements.
