Bitcoins are easier to pay than a debit or credit card, which can be accepted without a merchant account. In your wallet application on your computer or smartphone, enter the recipient's bitcoin address and payment amount, and you can complete the payment by pressing the send button. To make it easier to enter the payee's address, many wallets can be accessed via qr code scanning or NFC technology.
Do you think it is convenient to use bitcoin?
Yes they are but it is no different than what we have with credit or debit cards or internet banking for example. I mean you have to have the bank account for availing these services but for using bitcoin there is no different thing there too. I mean you have to have the bitcoin wallet in the first place and on top of that you also need to synch it with the KYC now a days.
Thats about the account creating in both financial institutes!
The further steps are also kind of similar,
-> With internet banking you can send funds almost instantly by using services like UPI, IMPS, QR and much more.
-> With ATM cards you can have instant money in the form of cash or you can pay at the counter in zero minutes too,
For Bitcoin :
-> Similar way of paying, you need address and you need confirmation after transaction is broadcasted.
I think they both are convenient.
