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.
