Why BTC premium should be read with market breadth
Bitcoin is a useful benchmark, but Korean assets do not all trade at the same premium. Reading BTC together with representative premium, USDT premium and positive-premium breadth helps distinguish a market-wide gap from a single-asset move.
Which prices and exchange rates determine BTC premium?
The selected venue supplies the domestic BTC/KRW price. The global BTC spot reference is converted to KRW using separate USDT/USD and USD/KRW rates.
Premium (%) = [domestic BTC/KRW ÷ (global BTC/USDT × USDT/USD × USD/KRW) − 1] × 100
Global source and collection time
The fast reference uses a valid OKX spot price and is identified as a single-source reference. If this reference is unavailable, collection falls back to a path that compares several global exchanges. Check the BTC card's reference and source-count fields for the sources actually used.
The FX basis differs from using the local USDT/KRW price as the denominator. You can compare the two lenses in the premium scanner. The update time refers to collection time, which is also used for browser observations.
Worked example: what does a +2% premium mean?
Assume global BTC is 100,000 USDT, USDT/USD is 1, and USD/KRW is 1,400. The converted reference is KRW 140,000,000. A domestic price of KRW 142,800,000 produces a +2% premium. These assumed values explain the calculation; they are not current market quotes.
Changing the domestic venue, global source, exchange rate or collection time can change the result for the same asset. Compare global reference exchanges alongside the live scanner.
