If you are unable to get your coin deposit in your Bitkub Wallet, it is possible that your request is just delayed. Deposit request will pass through the Blockchain from your outside wallet to your Bitkub Wallet. Transactions in Blockchain will be transferred to your Bitkub Wallet once the confirmation is complete. All you have to do is to wait for it to be confirmed in Blockchain.
The confirmation of your coin deposits varies from each type of coins. You may check the table below to see our recommended deposit confirmation.
