The statement is well-supported by high-authority primary and secondary sources. The definitive primary source, the CoinShares digital asset fund flow report, shows year-to-date inflows for XRP investment products at $21.8 million. This figure is nearly identical to the $21.81 million in the claim, with the minor difference likely attributable to rounding. Furthermore, a major financial news outlet, Yahoo Finance, corroborates the exact figure of $21.81 million, stating it as a daily inflow total on a specific date. While there is a minor discrepancy between sources on whether this figure represents a year-to-date total or a single-day inflow, both scenarios support the core assertion that clients of these funds 'acquired' holdings of this value. The existence of the investment vehicles themselves (ETFs/ETPs/Trusts) is confirmed by primary sources such as WisdomTree and the DTCC, establishing the mechanism for such an acquisition. The combined weight of the evidence from the primary data provider and major financial news outlets makes the statement highly credible.
