I would prefer that I could pay with Bitcoin all my bills
If you pay your bills by credit card then there is an opportunity for you.
There are many kinds of bitcoin debit card which you can easily spend your bitcoin and get instant into cash or spend online like normal credit cards.
That's not quite the same thing, it involve extra steps in purchasing the card and funding it, and in the end you have all the same security concerns as you do using any other card based transaction.
I want to be able to pay my bills with btc, too, but I want to pay directly from my core wallet to the purveyor's address. This would allow me to collect rent from out of town renters via bitcoin, removing the time delay of mailed payments, and turn those rent payment right around to the bill collectors. No middle steps, no cards, just bitcoin.
