From the close at the start of each period to today’s reading at 20:10 UTC. History, not advice. Pick a period to see what a purchase then would be worth.
Ref. 01How this is worked out
- Every buy is priced at the close of its day in the registry’s own daily history: the last price of the UTC day, backfilled from the exchanges’ own daily candles and then recorded by the registry. Today’s figure is the latest reading so far.
- A buy on a day with no close on record happens at the next close there is. The end is the last close on or before the end date. A close more than three times away from the days on either side is left out as a glitch.
- No fees, no spreads, no taxes. The coins are bought and held, never sold.
- This is what the history says. It isn’t a forecast, and it isn’t advice.
