BitNational CryptoATMs often support instant redemption of withdrawals, and at most require just one network confirmation. Network confirmation time varies by digital asset and chosen network fee. A higher network fee will decrease wait time for redemption. Many wallets have preset fees that range from "economy" to "priority". Some wallets have a "custom fee" option for advanced users. Most wallet's carry a standard fee that gives a confirmation within an hour.
