I know math is hard for you and you don't understand what an "FPGA copy" is, much less why HashFast's chip is more advanced.
Just forget about all the confusing things going on under the hood and focus solely on the output, like a good consumer. Leave the icky details to us hardware nerds and you'll do fine!
You brought math up in your defense?? Let's see how well that works out for you.
KNC 1Th example using about 1W/Gh (rough numbers to prove the point)
Oct Output: 50 BTC (use a low $300 per BTC) for $15,000, less the $150 power costs. (1% of revenue)
Nov Output: 30 BTC for $9,000 less the $150 power costs (1.7%)
Dec Output: 15 BTC for $4,500 less the $150 power costs (3.3%)
So if you got your wonderful 1/3 less power costs in October you save $100 per Th. which is less than 1% for that month
But of course you didn't..If you got your wonderful HF miner in Nov you save $100 per Th per month but down $15,000 for being late to the party (over 12 years to make up difference @ $100 month savings)
If you got your wonderful HF miner in Dec you save $100 each month but down $26,000 for being late (over 21 years to recoup)
If you got your imaginary HF miner in Jan you save $100 each month but down $30,500 for being a derp (over 25 years....)
