The only unusual thing about this is the debit card part of it, many banks are banning transactions on credit cards as they fear that users will not be able to pay off their debts if cryptocurrencies go bust and also that cryptocurrencies can be easily used for fraudulent activities.
Well yes I agree with you, if Cryptocurrency is made like that then the answer is not allowed.
Something that is made for fraud is not good.
If cryptocurrency is made for good, the results will be good too.
