Earlier quoted context omitted.
This seems insane. If I build 3 chairs I do not include the market price of 3 chairs on that day in my gross income, I sell the chairs and recognize the income generated by the sales.
Bitcoins earned through mining are considered compensation for providing resources to the Bitcoin network to compute hashes verifying transactions. IOW, it's not at all analogous to building 3 chairs yourself.
In practical terms, I'm not worried, as I suspect that I'd have a net loss, but assuming a net gain (that the fair market value of the parsley and sage I got from the herb garden exceeded my out-of-pocket costs to run the garden), I think I have to file a Schedule F per the regs.
For the record, it seems perfectly consistent to treat BTC as capital property; it doesn't seem reasonable to treat them as ordinary income.
