Every deposit needs network confirmations twice: first before you can trade the deposited funds, then before you can withdraw them. This article lists both numbers in two separate sections.

How network confirmations work

As soon as a sender transfers funds, a transaction enters the network to be completed and included in a block. It is the process of adding the transaction to the structure of a found block, which is called the transaction confirmation. The transaction confirmation process is necessary to prevent the same funds from being spent more than once. One new subsequent block equals one confirmation. 

Once your transaction reaches the minimum number of network confirmations, you can trade on the Spot Market and transfer funds from your Main Balance to your Trading Balance and vice versa.
Once your transaction reaches a sufficient number of confirmations, it receives the "successful" status and is credited to your balance, after which you can perform any actions: from trading to withdrawing funds.
 

The confirmation process speed depends on various factors, such as network load, transfer fees, speed of your internet connection, etc. On average, it takes from 30 minutes to several hours for a transaction to be confirmed. However, sometimes it can take from 2 to 14 days if the network is overloaded. 
 

Please note that the number of confirmations required for actual depositing of funds or trading is determined by every receiving platform individually, for each particular currency, according to its own security standards.

You can check the status of a transfer and the current number of confirmations by the hash (ID) of a transaction in a corresponding explorer. You can go to it through the Balance page by clicking the chain icon next to the corresponding ticker.
