The ban on anonymous transactions in Korea has made many trading floors difficult and forced to temporarily suspend transactions.
this doesn't make any sense to be honest!
first of all transactions to and from exchanges (trading floors!) are not anonymous at all. as soon as you sign up on these exchanges specially if they are working with fiat deposit/withdrawals in addition to cryptocurrencies, your anonymity goes out the window.
second you said they stopped working but they are still active as far as i can tell. and regulations have been happening for some time now.
