I want to ask a question, if there is a Bitcoin ATM card, and you want to use it to pay bills such as an hotel booking, will the payment reflect instantly while the atm machine or Miners still has to process the transaction?
Probably you dont need a physical bitcoin atm card, since bitcoin is digital and used to transact with different establishment.
I am using my btc to pay for some of the hotel, airline ticket and some reload balance so I cant say this can be considered yet as a currency but I am grateful for it as payment method to which I am always need. Some can say its not that worth it but for users like me. It is very useful.
Imagine if I have to pay for a service and its taking longer before confirmation of payment.
That's not an issue for some stores and restaurant that accept
BTC. Yes the payment could be delay but the tx has been done. It's just needed time to be process. Well scalability must be improved. There are many users that using the network is a prove that adoption is increasing.
2nd layer solutions like Lightning brought instant confirmations.
