I'm talking as major as it was to switch from CPU to GPU. Will there realistically be any such advance before we mine out all the BTC?
The rise of ASIC mining chips is going to be a pretty big jump, but after that there is no major advances foreable.
Exactly. What else could there be after ASIC which is specially designed CPU that is a dedicating mining chip?
Then who can design, build and sell the best arrays of ASICs I suppose.
