Protip: If you would like to keep Bitcoin mining decentralized, don't invest in mining companies.
I have to agree with Lambchop here.
Lambchop is saying that people shouldn't invest in AM. Do you really agree with that or did you just not understand what he was saying?
I agree that if you want mining to be fully decentralized you shouldn't, however I think that if their hashrate is 10% or less there is no real risk. So its a mixture.
Lambchop is basically saying that ASIC miners should not exist, regardless of whether they're used by individuals in a P2Pool or by a corporation solo-mining with 40% on the network hash rate.
AM isn't just building a huge mining operation, well at least they didn't want to. Now it seems they might as well just do exactly that. But effectively, they're producing chips that other mining operations use. So as a chip manufacturer it totally doesn't affect a decentralized system.
What I said in no way implied that selling ASIC miners causes centralisation. I don't know how you got to that from what I said.
What I was saying is that in order for a company to create and sell ASIC miners, it would need investment. Lambchop is saying that nobody should invest in mining companies. Without that investment, mining companies would not exist and neither would ASIC miners.
No investment in mining companies == no ASIC miners.
