i think s4/s5 are still very profitable if utilized correctly!
you mean if you heave very cheap electrcity, there is no other parameter to have to "utilize correctly" those miners
diff will skyrocket now with the new btc price, those miners will be useless in no time for small farms
They can only pump out so many machines. With new price I think it will keep many profitable for quite a bit.
There are only data centers so they could build more that is true, and I'm sure some are. But with a spike like this it could as easily go other way, so I don't think we will be seeing you are thinking. Also hashrate is so high it takes quite a bit to move it. I mean were in 5+ right now and huge gain on value.
