This list shows coins against USDT that are up or down more than 3% today on at least twice their 21-day average volume, with an average true range above 3% of the price, heaviest relative volume first. These are the coins with the most trading activity today. Crypto trades around the clock, so the list uses near-real-time data with daily bars that close at 00:00 UTC, and covers coins quoted against USDT with at least 1 million USDT in average daily volume.
