The claim is well supported by the fetched CoinDesk article, which directly states that Morgan Stanley's new MSBT fund drew more than $100 million in its first week and did so with a 0.14% fee described as the market's cheapest product in the category. The same source also says this intensified competition and specifically mentions Goldman Sachs filing for a Bitcoin Premium Income ETF. The SEC filing titled Goldman Sachs Bitcoin Premium Income ETF independently supports the Goldman competitive context. Yahoo Finance provides secondary corroboration of the $100 million and low-fee points. Confidence is medium rather than high because the central quantitative claim relies primarily on a news report rather than a directly fetched Morgan Stanley press release or fund filing showing first-week inflow totals.
