I am aware of the difficulty issue. The only miner NiceHash uses where my limited capacity is easily able to track difficulty is CUDA, and at a difficulty of 512 with CUDA I am making less on my test machine with the latest version than I was from version 1.7.5.12, and as I said, from other research I've conducted, this is based on a virtual memory allocation issue I'm not smart enough to understand. But that doesn't even matter anymore because my funders won't sign off on a miner that comes with a legal notice like the one the latest version does. So yes, for once and for all, the version does matter. In this particular case.
It would be so nice if people read what I was writing, or if they weren't willing to bother to do so, then at least wouldn't bother replying.
You still don't understand.
The difficulty that you see in your miner software is the minimum difficulty that your GPUs need to find to be able to submit a share. This has NOTHING to do with your overall income. Its purely for bandwidth reasons so faster miners don't flood the servers.
A faster miner will submit the same amount of shares as a slower miner but they will carry a different difficulty weight. You might submit shares at 512 difficulty and someone with 10x the hashpower submits shares at 5120 difficulty.
They really should of called this differently because it confuses many new people.
The point is you can just as easily use a Claymore miner software and mine ETH or ZEC directly and then sell that ETH or ZEC on Shapeshift or on some exchange and get your BTC and then later sell BTC for US dollars.
That's not the issue. The issue is that you are making it mandatory to "Exceed 2mBTC per 1070 per day", that's not going to happen.
What does mining term mean to you? Think of it like mining for Gold. Everyday you mine the same amount of Gold. Then the next day you have 1 other person who joined mining with you, what happens? Right now you only mine half of what you mined before, because you got competition. Mining is the exact same.
Tell your investors that they can make 1mBTC per day per 1070 today, in 2-3 weeks they might only make 0.5mBTC and in 2-3 months they will only make 0.25mBTC per day. After that you can sell the hardware on eBay and all your profits will go to the kids.
You won't get rich but you will maybe make a little profit. And it will be a fun learning experience and great hobby. Good luck.
