I don't know who do you remember saying that but... 1$ / day / 1070 sounds a bit too high for me, these days only a 1080ti gets you at around that much, and that's before you subtract the electricity.
Also note that a 1070 will be outperformed by a 1070ti in HEX algo. Don't be confused with Ethash in which the difference between the ti and non-ti versions are minimal.
Mining cryptocurrency is currently unprofitable. even for large mining farms. which is all optimized. What then to speak about small single miners ...
