1h (1 Hour)

1h (1 hour) is a column label used on cryptocurrency price and market-data sites to show a figure measured over the most recent 60 minutes, most often the percentage change in an asset's price. The window is rolling: it compares the current price with the price exactly one hour earlier, so the number shifts every time the page refreshes rather than resetting on the hour. Timestamps on these sites are usually kept in Coordinated Universal Time (UTC). Because an hour is a short span, the 1h figure mainly reflects short-term volatility and noise, and a large move in thin markets can come from a single big order. Traders read it alongside trading volume to judge whether a move has real activity behind it. Also see 24h (24 Hours) and 7d (7 Days).
