Who's that coin?

The rules, all of them

The coins

The most-traded perpetual markets on Hyperliquid, ranked by average daily volume over the last 7 days: the top hundred that pass the rules. Crypto only: the exchange's own markets, not the stock, commodity or pre-IPO markets that outside builders run there. No Bitcoin (it is the faint line on every chart), nothing pegged or gold-backed, nothing that moves as a copy of a bigger market. The guess box offers exactly these coins. See the list

The chart

Daily candles for the last 90 days, ending 00:00 UTC today. They are the prices of perpetual contracts on Hyperliquid, which can sit a little away from spot prices. A market listed more recently shows what exists, at least 30 days. The scale is percent change from the first day. Only the name and the price are hidden.

The answer

Picked by the site, not by a person. Each day 20 coins are drawn from the list, and the one whose 90 days stray furthest from Bitcoin's is the coin of the day. No coin comes back within 21 days.

A miss

Tells you whether the answer is a bigger or a smaller market than the one you tried (more or less traded, by the list's rank), or that it sits within 10 places of it. The coin you tried is drawn on the chart next to the mystery one.

Hints

After the third miss: how far the coin closed yesterday below its highest price of the last year, taken from the same daily candles. After the fifth: the first letter of its ticker. A skipped try counts as a miss.

The check

Each guess is checked on the server. This page gets candles only, and the name arrives when you solve it or after try six.

The honest part

A chart that ends today can be looked up. Nothing is at stake here: no prizes, only your streak, which lives in this browser.

The list is rebuilt by the site every week, starting Monday 00:00 UTC, and the new list is used from the next day's coin on.

Your record

Kept in this browser only. Miss a day and the streak starts over.
