I also saw prices are increasing.
All miners exept the S9. Theire prices are still the same
That mean some sleeping miner come alive so although the price is up but there are more mouth to feed
Because there are so many S9's being plugged in across the world that the price appreciation in BTC and BCH have barely moved profits. Sign of the times. Just wait....there are many many more S9's coming online from the "corporate miners". The bodies of small and medium miners will soon be stinking up the landscape. The irony is palpable. The greatest decentralized protocol is being destroyed by hierarchical corporate greed and scum. Same flies.....different shit.
Corporates coming in is fine. The problem is if it gets controlled by a handful of corporates. This would mean the prospect of a 51% attack is real. Bloomberg made a story about this also. The problem is that if news that it has occurred and mining is centralized among a few players, that means a 51% attack is possible and just the news could crash bitcoin. Problem is we are all hodlers...
I wouldn't worry so much about corporates. They are pretty incompetent and unknowledgeable when it comes to crypto blockchains. Remember that Kodak tried to offer their own bitcoin mining ASICs which were simply a rebranding of bitmain ASICs? Until crypto matures and blockchain developers become a regular job, corporations probably won't have any real technical capability to harm the current ecosystem we have.
