Deposit and Withdrawal Status

Each exchange's official API (Upbit, Bithumb, Coinone, Digital X) is checked every 5 minutes for every coin in its KRW market, and only the coins with closed deposits or withdrawals are shown. Announced suspensions, and Coinone and Digital X warnings and delisting dates, come from the exchanges' notices. Before sending a coin, check both the sending and the receiving exchange's wallet screens and notices: a coin sent while deposits are closed may not be credited, or may need a separate recovery request.

Each exchange lists a different number of coins (Bithumb has the most in its KRW market) and runs its own wallet maintenance and network work. Warning policies differ too: some, like Upbit, close deposits as soon as a coin gets an investment warning. So a coin is often closed on one exchange only.

Closed on several exchanges at once usually means the coin itself has an issue, such as a network upgrade or failure. Closed for a long time on one exchange only can mean that exchange's wallet work, or a trading-support issue like an investment warning or an upcoming delisting. The "Warning" and "Delisting" notes and the "Notice" link in the table show the reason.

It can be negative: when the Korean price is below the overseas one, the premium is negative, a reverse premium. On a coin with a closed wallet arbitrage cannot close the gap, so the premium or the reverse premium easily grows larger than usual, and such numbers are usually hard to actually earn.

Wallet status is checked every 5 minutes, and the page refreshes itself every 5 minutes while it is open. Announced suspensions and warning or delisting notices are added within 30 minutes. The times are when CoinGaja first saw the suspension, so the real start can be up to 5 minutes earlier.
