I agree that Chinese control ASIC mining. Maybe is next step to change the mining protocol from sha256 to some GPUs.

If Bitcoin or Cash wants to become number one crypto, it should support instant transactions.  

Cash doesnt support instant transactions. With Bitcoin SegWit we get instant transactions and that all it counts.

If Bitcoin becomes global currency, even 8MB blocks will be much much smaller than needed, so whats the next step? 32MB, 64MB, 1GB blocks,...

@Aztek:
Sorry, but I think you don't understand technical aspect of Bitcoin protocol at all. For scaling Bitcoin transaction, mining bigger blocks is nonsense. Old Bitcoin  supports 7trans/sec, Bitcoin cash supports 50 trans/sec, Visa can do 10.000 trans/sec. Who the king?

I thing the one who could handle more and make confiramtion quicker. Maybe SegWit  is solution.
