0.0015 BITCOIN?! ... for Keurig coffee ? I'm sorry but I'm not spending more in bitcoin on mere Keurig coffee than an amount I might be able to GPU mine with a spare laptop in a weekend.
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.
