I would say it totally depends on the situation or what type of good your are purchasing.
Bitcoin payment is surely convenient but unlike debit card, all dont accept it. and even in future why would people take the pain of accepting bitcoins when they want is fiat only which can be done with debit card. people wont take the effort to accept bitcoin and convert it to fiat
What do you mean "effort"? Accepting bitcoin payment is painless, fast ,cross borders, no charge back risk. What you only need is to show our address to the senders. The payments processors will take care of all of the other things, cover the bitcoin to fiat, transfer to you bank.
