Here are the possible reasons:
The block hasn't been confirmed by the miners
Once you submit the withdrawal request, your funds will be submitted to the blockchain. It requires miners' confirmation before the funds can be credited to your account. The number of confirmations can be different according to different chains, and execution time can vary. You may contact the corresponding platform for verification if your funds haven't arrived in your account after confirmation.
The funds are not withdrawn
If the status of your withdrawal appears as either "In progress" or "Pending withdrawal", it indicates that your request is still waiting to be transferred from your account, likely due to a large number of pending withdrawal requests. Transactions will be processed by BloFin in the order that they're submitted, and no manual interventions are possible. In case your withdrawal request remains pending for more than an hour, you can contact our customer support team via BloFin Help for assistance.
Mismatched withdrawal network
Before you submit a withdrawal request, please make sure that you've selected the network supported by the corresponding platform. Otherwise, it could lead to withdrawal failure.
Select the withdrawal network that is supported by the corresponding platform in the Withdrawal network field. For example, you would like to withdraw crypto from BloFin to Platform B. You've selected the ERC-20 chain in BloFin, but Platform B doesn`t support the ERC-20 chain. This can lead to withdrawal failure. In such a case, you need to contact Customer Support of the receiving exchange for further assistance.
The amount of the withdrawal fee
The withdrawal fee that you've paid is to miners on the blockchain, instead of BloFin, to process the transactions and secure the respective blockchain network. The fee is subject to the amount shown on the withdrawal page. The higher the fee is, the faster the crypto will arrive in your account.
