If you have not received coins on GOPAX.COM even though the transaction status shows as 'completed' or 'success' on the exchange you are sending from, 

it means the coins were transferred successfully to the blockchain network, and the blockchain network is transferring the coins to GOPAX.COM.

Transactions may be delayed if the blockchain network is congested with many transactions.

In this case, you can check transaction progress and confirmations on blockchain network using TxID.

Transactions will be fully processed after a set number of confirmations are made.

Number of "confirmations" before a transaction is verified may differ for each coin. 

Please see the table below for the number of confirmations and blockchain websites of each coin. You may check transaction status and confirmations by searching TxIDs.

< Example: How do I check the transaction status and confirmations on the Ethereum blockchain?>

1. If you have sent coins to GOPAX.COM from another exchange, please check TxID from the exchange you are sending from.

2. Visit the Ethereum blockchain website(https://etherscan.io/) and search by TxID.

3. Check confirmations and transaction status. Transactions will be verified and deposited to your GOPAX.COM address after all confirmations are made.
