Cryptocurrency is stored in a digital wallet, a secure environment that stores the private keys you need to get to your bitcoin and other crypto.
Bitcoin network fees, or bitcoin mining fees, refer to a sum that is charged to complete a bitcoin transaction. These bitcoin fees are tacked onto the amount that the sender inputs and added to the total transaction amount. Like the bitcoin network itself, bitcoin fees are dynamic. When the bitcoin network gets busy, or when there are more transactions happening, the bitcoin network fees increase.
