Do you think credit/debit cards will still be a thing after the launch of CBDCs? If not, why? Will payment processors like PayPal, Visa, and Mastercard survive? Your input would be greatly appreciated. Thank you. 
Already the use of credit/debit cards have already reduced since mobile apps banking platforms have been put in place such that everyone can use their mobile phones to makes purchases of goods and other items but their are still payments that requires this credit/debit cards to authenticate payments however this medium of payments have a credit and debit limit which can be frustrating when you want to make large payments that is why Bitcoin will be the end of this debit/credit card because it has not credit limit or withdrawal limit.
