The date is part of the number
Imagine two readers comparing a fund at breakfast. One is looking at its closing share price. The other has a holdings spreadsheet. They think they are discussing the same snapshot, but they may be comparing different dates, valuation conventions and units. More decimal places will not resolve the disagreement.
The iShares IBIT product page publishes separately dated fields for holdings, net assets, shares and market information. Its notes explain that some holdings information reflects an investment book of record and may differ from accounting records used for net asset value. The source is telling us that context belongs beside the data, not in a forgotten footnote.

Stock, price and movement
Holdings describe an amount at a point in time. A share price describes what a security traded for at a specified moment. A flow describes movement over an interval under a defined method. Calling a rise in a dollar-valued holdings table an inflow can confuse a change in price with newly committed money.
A simple fictional example makes the distinction visible: ten units valued at $2 have a value of $20. If the price becomes $3 and the unit count is unchanged, the value becomes $30 without an additional unit arriving. A real fund has fees, creations, redemptions and other accounting details; this teaching example deliberately omits them.
Compare instruments before comparing charts
ETF and ETP labels are a starting point, not a complete description of a product. The issuer materials, legal structure, jurisdiction, listing currency, fees and underlying exposure deserve their own fields. Cross-listed instruments also need a stable identifier so a dashboard does not count the same product repeatedly.
LTC links both the IBIT issuer page and CoinShares’ Physical Bitcoin product materials as primary product references. These links are not endorsements, and a successful source retrieval does not mean we have validated every financial field or built a comparable flow series.

How we want the daily desk to work
Our collector keeps the source-effective date separate from the time it fetched a file. The published source panel is a stored observation, not a live terminal. A missing or failed observation remains missing; it does not become zero. Daily collection and daily editorial publication are separate jobs.
Before adding a new financial chart, we want another person to reproduce one point from the linked record. If that cannot be done, a smaller table with clearer limits is the better public service. The goal is a reader who understands the evidence, not a reader impressed by the number of tickers.
