The amount of time it takes you to create a US Dollar isn't how you would measure the cost of something. It's strictly based on the value of that item. And with .0015 Bitcoin being equivalent to just over $1 USD, it's not much markup. A k-cup can easily cost $.75/each.

I get mine from amazon for about $.50/each. Once I found a bunch on clearance at kroger's, and then I had $.10/cup coffee for about half a year.

Less if you go the box-o'-cups-at-Costco route like I do. It can be economical if you don't mind just-OK coffee.

The Costco varieties are the same as the ones I buy anyway, so to me it's a win-win.
