I don't see how 1 is any issue at all. Using a computer to make the intended bitcoin calculations much faster than anyone else possibly can is entirely within the rules of how bitcoin works.

It will also tank the price because by doing it, you have demonstrated you have complete control of bitcoin transfers, you can transfer bitcoins from anywhere to anywhere else at any time, and that there is no way to flag it as illegitimate because mathematically you're just providing the correct numbers.
