On August 28th, according to statistics from Coinhills.com, the US dollar is currently the legal currency with the largest volume of transactions with Bitcoin, and 64% of the legal currency that BTC trades every day is US dollars. But that doesn't mean the dollar dominates because many international crypto exchanges offer dollar trading pairs. The yen ranked second, occupying a 22% share. The third place is South Korea, and the Korean won accounts for almost 10% of the total. The euro is ranked fourth, but it only accounts for 1.5% of all bitcoin transactions. Statistics show that Asian fiat currencies are clearly dominant in bitcoin trading, especially in Japan and South Korea. Since China's transactions are mainly over-the-counter transactions, it is impossible to measure China. If China and India are included, Asia's dominant position may be higher.
