“Bitcoin *is* a convenient medium of exchange—blockchain transactions are quick and lack transaction costs.”
ABSOLUTELY! ... i use it for all of my daily transactions, from buying bottled water in a vending machine, washing my car at the local carwash, paying for hardware at Ace, filling up with gasoline at Shell, and paying for groceries at Safeway, Costco, Sam’s Warehouse and King Soopers as well as dozens of other locations ... it really couldn’t be more convenient than that!
Apparently you don’t bother reading the entire thread before posting. Multiple posters, including myself, have pointed out that Bitcoin is *not* intended, nor suited for, high-volume retail transactions.
