Do you understand what pre-order means?
Once you placed your pre-order*, you lose your choice to "not buy" if the price makes no sense. You either mine, or put your miner into a Hefty garbage bag & set it on the curb. If, by the time you receive your miner, it becomes blatantly obvious that said miner will never ROI, wat do?
*KNC pre-orders made through PayPal leave open a refund option, but that's not the case for most pre-orders -- those are locked in.
Huh? Your point now is that if we'll never get ROI then we'll... what? Never get ROI? Thanks for that brilliant tautology.
The question here is about odds of achieving ROI which I said is very difficult to predict. Do you want to address that or not?
No. My point is people will continue to mine as long as the price of BTC is greater than the cost of electricity burned to produce them. This doesn't suggest anything close to ROI.
My secondary point: I'm willing to answer your questions, no matter how silly they are. What would you like me to address, now?
