I came to figure out, why would a consumer/customer use Bitcoins?
You have to pay the 3 cent fee, while you dont have to pay anything when paying with a credit card.
So what is really a benefit for using Bitcoins, customer wise?
i think largest benefit is because bitcoin is very easy to use and they can pay in seconds, while they might search for monets in their wallets for 30 seconds or even more
Wait, they're shopping in a brick & mortar store (99% of those never even heard of bitcoins, forget taking them), they don't have their wallet with them? But they do have their laptop and/or smartphone with a bitcoin wallet? That happens how often?
I got an equally realistic user case for you: You're walking through a shitty neighborhood teeming with bitcoiners jonesing for their DOC, bath salts, late at night. One jumps out from a garbage can with a knife, demanding bitcoins.
