Your transaction will be credited to your account once it reaches the minimum amount of confirmations on the blockchain. This amount is different for each currency and may be changed at any time, based on the stability of the network, the health of wallets, and several other factors.
The speed at which a transaction receives confirmations depends on various aspects, including the mining speed of subsequent blocks and the amount of transaction fees.
On the Deposit History page you can check the status of your transaction, including the current number of confirmations on the blockchain. If your transaction has reached the minimum amount of confirmations and it hasn't been credited to your account, please contact us via our Support Center and we will be happy to assist you.
