I think in 6 months there will be 6-10 large mining operations that account for 10-15% of the network hashrate. I think this is the logical course that's developing currently.
That being said I think only companies that can produce their own chips, or have access to a supply of incoming chips will be left as one of those 6-10 players. Eventually the arms race will end and those players will be the only ones remaining.
I also think ACTM will be one of them I see no reason why they wouldn't.
Highly recommend listening to the latest edition of LetsTalkBitcoin, that discusses this. Even Sir Gavin, has an opinion.
