Asic mining has hit technology cap.
There is little room left for whale to sequence what little profit margin left.
ASIC is far from the technology "cap"
There have been great advances in both ASIC technology and technology in general in only the past 5 years (ASICs have not been around that long but for technology in general, and in one year for ASICs).
It would be very unlikely that ASICs will not become more efficient both in power consumption and total hashpower that a single machine can produce.
