Nonsense. Long before Bitcoin was a thing, I dreamed of money with wildly fluctuating buying power.
I imagined a world where it took an hour to buy a cup of coffee, an hour to gas up your car, an hour to buy a bag of groceries... Because math.
Obviously you've never done any actual shopping with bitcoin.
I have never bought a cup of coffee with Bitcoin.
I have never gassed up my car with Bitcoin.
I have never bought a bag of groceries with Bitcoin.
It was just a dream...
If you have and it took an hour, then those places seriously need to rethink how they accept their bitcoins.
My payments go through instantly (zero confirmations required).
