I understand the convenience of being able to convert right away your coins/tokens into cash. But since you are being connected to fiat money. government rules and regulations should apply. To be fully operational, each government in every country needs KYC for every customer. So if you are going to be KYC free, then I doubt that the government will allow you to proceed with your project.
There might be KYC i think with CryptoRiya as a user im not sure with it but it is impossible to require kyf in every transactions. When we withdraw cash from our ATM card there is no such hassle of kyc. When we pay with debit card in malls or restaurant we are not being asked with any question, we just give the card and they give us the reciept back.
A KYC ( KNOW YOUR CUSTOMER ) is a must with this!
they will be dealing with cards and transactions. this will not be legal if there will be no proper documentation before releasing those cards.
purchasing and others will not have an identity, receipts are important to have too.
Also incase of card loss, it is important that you have your personal identification in the platform so they will have the reference or proof of ownership of the card. But i think for a s regular card which cost 25% and will have no monthly fees it will be enough if they will not require KYC, after all with the regular card they will not be allowed to cash out beyond the limit set to it.
