More than 800 South Korean companies have opened accounts with the domestic cryptocurrency exchanges.

The number jumped more than five-fold in three years although the Korean government does not recognize the exchanges.

The amount in their accounts topped 209.1 billion won last year.

Shinhan Bank retained 257 accounts, the largest, followed by IBK’s 136, KB Bank’s 120, Woori Bank’s 115 and KEB-Hana Bank’s 75.
