there has been some evidence posted that monero is mostly mined by a few large botnets. or so i have heard. idk where that post went though
I am 99.99% that half of Monero was not mined by botnets.
Now who are botnets? Unused CPUs.
So someone hacked your refrigerator to mine Monero for him. Yes HE is a criminal. Lets hope HE will pay his debt to society. But the coin has nothing to do with the hack of your refrigerator, since if your refrigerator would not mine Monero would mine some other coin or do some other calculation.
That is same as if bank robbers went to supermarket buy them self a sandwich. Without sandwich they would not be able to do a bank robbery. They used USD to buy sandwich and in also buy one. So with your theory, those that issue USD are scammers also the ones that produce sandwiches are a scammers.
Oh also internet is a Scammer since let those hackers hack your refrigerator.
