It doesn't matter what's more convenient for the producers/vendors/merchants. The consumers will use what is most beneficial to them, and the rest will be forced to play along.
All my credit card purchases appear to happen instantly and seemlessly to the consumer. Bitcoin transactions take hours to verify, which is painfully obvious when moving money around.
I am with you Info... BTC is great and all but it isn't the be-all end all for using to make purchases.
People want believe that BTC is "great" for merchant due to no charge backs etc... but these same features make it difficult for consumers to use AND it makes theft/scams even easier. What will happen is the credit card companies (or something similar) will start to process and insure BTC transactions so they can be instantaneous just like CC purchases. Guess what will happen? Similar fees just like CC transaction will be charged, hopefully a bit less though.
Good for large purchases? Yeah I can see that, faster and less expensive then wire transfers, mailing a check... a check?... no one uses those but that is basically what a BTC is, just a bit faster and with the times.
To those that think using BTC will "save them time" shopping online and relieving the difficult job of remembering accounts... is honestly just silly. I have made purchases at sites where you don't have to create an account and guess what... the only extra info you need to give them is a password. They have to collect all the info anyways, like where to ship, email for updates notifications etc. I suppose if you were purchase digital or non-deliverable items it could save typing your name and address (oh the horror).
As I said what will happen with BTC and normal buying is the same thing that is happening with CC/banks, people will have apps on their phone and will scan codes/bump etc to transfer funds. It will be cheaper until either the Feds get to regulating or the big corps come in like the CC companies and decide they should charge the same they always have.
