(for those who are looking to at least make their purchase money back)
Does anyone not fall into that category??
Seems foolish to not be looking for making
at least their purchase price back. I am hoping to make at least 20-50% ROI above hardware/power costs. The judgement call to keep the order or cancel (or go with some other option) all depends on what the total hash rate and resulting difficulty look like at the time the chips have arrived, boards are fully done and tested, and devices shipped. I'd say if the box can't be mining by August then it's likely going to be not worth the investment.
Personally, if the difficulty is above 45M I am planning to cancel or maybe sell my order to someone who is willing to mine with longer than 3-5 month time-to-ROI.
Patiently awaiting updates on the K16 board (which appears to be moving along) and from TH....
I've seen some people claim to not be doing it to make money, and not care if they make their initial purchase back; they say they're doing it to help the bitcoin network. While I believe that's possible, and my motivation is split between helping bitcoin and making a little money, I'm cynical and given the rampant greed I see surrounding bitcoin I find it hard to believe someone's spending money on hardware solely for the good of bitcoin and doesn't care if they make their purchase money back
Of course, if that's true it's all doomed anyways. If everyone is in it to make money and profit, eventually it will all go downhill. The only reason people want bitcoins is either hoping they'll increase in value or to spend them. Merchants only take bitcoin because they can get money from it (they have to pay their suppliers and most of the time that means fiat), and on and on. If everyone or even a huge majority is all trying to profit, the only way to profit is for bitcoin value to go up and up. If the majority of the bitcoin economy is speculation on rising value, it will drive itself to unsustainable heights and eventually burst. A lot of people will get burned.
There needs to be a larger ecosystem of merchants and services accepting bitcoin, otherwise it's just a bunch of people trying to profit and that profit has to come from somewhere. In this case it would be people buying bitcoins and they in turn are hoping someone comes along behind them and pays more so they can sell and get their profit, and on and on.
