Cryptocurrency payment support apparatus, cryptocurrency payment support system, cryptocurrency payment support method, and non-transitory recording medium
An apparatus includes an acquisition processing circuit and an identification processing circuit. The acquisition processing circuit acquires first exchange information, second exchange information, and fee information, the first exchange information allowing identification of a first exchange where a first user has an account, among exchanges that deal with cryptocurrencies, the second exchange information allowing identification of, among the exchanges, second exchanges where a second user has accounts, the fee information including information about remittance fees that are required for cryptocurrency remittances among the exchanges. The identification processing circuit identifies, among the second exchanges, a second exchange that requires a lowest remittance fee for remittance with the first exchange, based on the first exchange information, the second exchange information, and the fee information.
