Selling by arbitragers — who have been buying Bitcoin on international venues to offload at a higher price in Korea — also played a role, although the country’s capital controls and anti-money-laundering rules made it difficult to execute such transactions in bulk.

The country’s waning frenzy has been reflected in declining activity on domestic exchanges. Data compiled by show that volumes have dropped by about 85 percent from December highs…
