Methodology

For KRW the series is the Bithumb Spot USDT/KRW price compared with the USD/KRW reference, (price ÷ reference − 1) × 100. It is an exchange order-book price, not P2P ads, so one series covers both directions.

Samples are taken every 30 minutes (UTC :00 and :30). Daily average, minimum, maximum and close use only the successful samples of each UTC day; failed or empty requests stay in the files with their status but are left out of the statistics.

Outliers: a short excursion (at most four consecutive samples, two hours) that moves more than 5 percentage points (more when prices are widely spread) away from the level both before and after it, then returns, is left out of the daily figures. Steps to a new level and the newest samples are never excluded; nothing in a UTC day is excluded if more than one sample and a tenth of its samples would be flagged. Flagged samples stay in the 30-minute files with outlier=true and count in the daily outlier_samples column.

Coverage starts on August 6, 2026. No calendar day is missing in this range.

The FX reference is an independent USD/KRW rate; when available, its provider is stored per sample in the fx_source column of the 30-minute files.

A premium is not a profit: trading fees, transfer costs, payment limits and execution risk are not included.
