Keep in mind, botnets are not free either. The "owners" of these botnets face opportunity cost like everyone else.
There are costs associated with everything. These costs, though, are more than made up for through the other activities of the botnets. DDOS, keylogging/identity theft, ransomware, spammers, etc. Mining is a small portion of it, but one that is adversely affecting this market.
They mine and dump and so the botnets may profit, they do so at the expense of Invictus which would be ridiculed for pre-mining if we had simply sold into the market.
Then maybe you should get in touch with the pool operators, share your vision, and get them on board.
As it stands now, botnets are hurting you but helping pool operators that allow them.
