BTC is not a transaction type of currency, it is a store of value currency.
I prefer to think of it as a value transfer system.
Most people other than speculators who use Bitcoin, use it to send money quickly and cheaply to other parts of the world, at least at this time.
Making retail purchases with Bitcoin is still basically a gimmick.
Bitcoin is the only thing I ever use to make retail purchases. Almost any purchase actually. I am at about the 98% point when it comes to bitcoin vs fiat spending. Now that I can buy my food with bitcoins all of my basic necessities are covered.
