What this rests on

Summary in preparation.

Market reaction

We track ETH, but we only have 1 price point in that window. The series is stored every half hour, so newer events will have it. Computing it from two points would not be a reaction, it would be a coincidence.

How the story was built

Every piece in order, with the time its news medium declares — if it is not believable we use ours and say so — and what it added to what was already known at that point. Arriving first is not the same as adding something.
