Note: Network fees are not charged by CoinsPaid.
Network fees are charged by the blockchain to process transactions. Every time you make a transaction, you're also paying a network fee. Both deposits and withdrawals are blockchain transactions.
The higher the fee, the faster the transaction will be processed. If the network is overloaded, the fees also get higher. When you initiate a transaction, CoinsPaid automatically calculates the optimal fee based on the current network conditions.
