Morgan Stanley's first physical Bitcoin ETF has begun trading on NYSE Arca under the ticker MSBT, marking a direct stress test on its opening day: can a bank-backed fund attract capital inflows solely because it is cheaper in a volatile market? Industry data shows that approximately 1.6 million shares were traded on the first day, and depending on the tracking target, the net inflow was about **$30–$34 million**. The fund's fee rate is 0.14%, making it the lowest-cost physical Bitcoin ETF in the U.S. market. Over the next two days, the newly launched MSBT ETF attracted an additional capital inflow of over 31 million dollars ($31.20 million).
