All I'm thankful for is I didn't preorder those 1TH+ miners... with the difficulty this high and now daily mining being taxable as ordinary income (and not when btc are sold/exchanged) and with cost of hardware and power, there's no ROI left. IRS has essentially gifted mining to the Chinese.
The only way you'd owe taxes is if you
were making income by mining (by definition!).
From what I understood, that's only if you file "self-employment", then you can include expenses like hardware and power and then it will all net out plus some writedowns ... if not, then its just ordinary income (although obviously a monetary loss with costs and taxes included)
