I just dont know if CryptoRiya will offer a minimum amount of charges from their user. But in my opinion, it is good if we can set the time interval of remittance to the exact payment in order to make a transaction successful.
Conceptually, svendoto has a point there in terms of CryptoRiya wanting to be global (though not directly as remittances) but of an exchange that you can cash-out any (yes any crypotcurrency, in the sense that the currency should be listed in CryptoRiya) cryptocurrency anytime, anywhere.
Charges and Fees are always a part of any services such an exchange, and according to CryptoRiya's whitepaper, ATM Withdrawal Fees will be 2% for regular CryptoRiya Debit Cards and 1% for the luxury ones (which will require a KYC).
