This model on the price scale0.5 to 25 across 3 published values

Price history

Every distinct value this price has taken, oldest first — what the price did, not how often we happened to look. Rows marked backfill came from a public git history of a third-party pricing file and were never verified by us; they extend the series backwards and are flagged rather than hidden.

1 distinct value

One value across the whole archive: this price has not moved in anything we have observed.

Held steady12 days — the value published now has been observed to hold for 12 days, which is 100% of the longest run on this page.
