In my neighborhood there are bars that accept Bitcoin. I've paid several dinners with my Android BTC wallet. Quite convenient in a city where you usually can only pay with cash...
Quick question - from someone who hasn't looked at bitcion since it was between 10c and $5 - since your transaction doesn't clear until the block propagates how they handle double spends?
Are you just listing a few random ways that Bitcoin is more convenient than cash? The OP was about spending money at a bar.
But okay, here's how cash is more convenient: I can walk outside my office and use this dollar bill at any store anywhere around me. It has apparent value to everyone I will talk to. I don't need the internet.
If you need to "program" or "backup" your money, I guess Bitcoin is your medium. No argument there.
