The number of foreign nationals with accounts at domestic cryptocurrency exchanges has reached 560,000, but only 90 of them are active users, data showed Sunday. The accounts are believed to have been opened before foreign investment was effectively banned in 2021. According to data from the Financial Supervisory Service, the five major cryptocurrency exchanges — Upbit, Bithumb, Coinone, DigitalX and GOPAX — had a combined 566,352 accounts held by foreign nationals. The data was obtained and released by Rep. Park Sang-hyuk of the ruling Democratic Party of Korea. Of these, only 517 foreign-held accounts, or 0.09 percent, had completed know-your-customer verification. The number of active accounts that recorded at least one trade, staking transaction, deposit or withdrawal last month was even lower, at just 90, or 0.01 percent. Bithumb had the largest number of foreign-held accounts, at 484,846, followed by Upbit with 42,449, Coinone with 15,914, DigitalX with 11,622 and GOPAX with 11,521. Korea effectively barred foreign nationals from investing through domestic crypto exchanges foll
