Provide your estimates then, since I can't see a mistake in mine.
I have exact calculations I'd rather not post but I'll do a back of an envelope here.
BCN block reward in coins is about 6400 times the XMR reward. The value of XMR is about 40000 times BCN. Combined these make the BCN reward worth about 16% of the XMR reward. The difficulty of XMR is about 10.5 times the difficulty of BCN. So by these numbers if you do 1/10.5 as much work you can get about 1/6 of the reward. Better to mine BCN.
This ignores other second order factors such as orphan rate, etc.
Do you really think that a botnet is just a mining gear? And rape is just a form of sex, right? Anyway, I'm pretty sure that botnet owners don't hold the coins they've mined as there are risks associated with the waiting game and you might have used your botnet for other purposes instead.
From the point of view of the rest of the network, it gets the job done and is indistinguishable from any other gear. If I owned a computer that was botted, I'd sure have a grievance, but no one else can really tell the difference. BTC or LTC do not suffer from being heavily mined on botnets at times (even currently to some extent in the case of LTC).
Your rape analogy is a bit strained, but to strain it further, if a rape occurs and a child is born, do you continue to associate the child with the rape? Coins are coins, and where they come from doesn't really matter to anyone else. That's what fungibility is all about.
Coins generated are either sold by the miner (almost always in the case of large scale professional miners) or held (sometimes by small scale miners and occasionally by large investors who have their own mining operations). That is the distincton that matters in terms of economics, and even that one doesn't always matter (if there are investors who prefer to buy than mine), as I explained earlier.
And I'm not trying to troll, but do you operate a botnet yourself?
No.
