Block confirmation is the act of a block miner to package your transaction data into a data block. It is a necessary step for your transaction (deposit or withdrawal) to be added to the blockchain, which means that a transaction will not be considered successful until the block confirmation reaches a certain number.
As different cryptos are based on different blockchain network, the minimum number of block confirmations required for deposit and withdrawal may vary. Please see the BIT's requirements for minimum block confirmations in the table below.
Note: The following information is for reference only, the number of block confirmation is subject to the latest changes.
