asics will destroy his operation
, botnets wont be profitable any more
I don't know about that. He had a relatively small botnet. Unfortunately, botnets are a thing that tends to scale well -- up to a point. Further, there is no margin cost for adding another bot to the network. Another user becoming infected and mining would all be automated. ASICS merely provide incentive for botnets to get bigger. Plus, the existing botnets at smaller sizes are going to become LESS profitable, but still profitable. Hashing power is still hashing power. So, there is still incentive to spend $5 for a 500 node botnet. Crime pays after all -- until you get caught.
