Bitcoin mining has come a long way, starting from plain old CPU's to blazingly fast ASIC's.
However, Silicon will reach its limit ( albeit in a long time
) and the age of ASIC just might be over.
So what is the future of mining beyond ASIC's? Are their any other viable options?
I've seen graphene, but it looks too new to implement a fully operable mining ASIC.
Quantum Computing looks tempting but that's really stressing a Venture Capitalists wallet.
