^^^ I mine bitcoin for pizza
Well I paid 128 BTC for a BFL FPGA miner ... long ago

obviously, if you spent 128 BTC on a miner (long ago), it is well understood that you did so with the premise to mine at least 128 BTC (and some!) with that machine...
hence, no issues....
Lulz, no I've no idea how much it mined.
Like all the other miners I've got, it's been to support them and their drivers.
I have rejected being given miners on more than one occasion due to disagreements with the people who made them.
Over time I've had way, way more BTC than I now have.
My interest has been BTC, not gathering truck loads of it (or money either)
i get that... what i meant was that value is relative...-and quite distractive.
