Even bigger asic mining company CEO being truthful about what is happening actually.
MegaBigPowers CEO Dave Carlson about centralization with asic bitcoin mining:
Centralization remains an issue
The rise of the ASIC and the profitability shifts for mine operators has resulted in what can only be called the death of the retail bitcoin miner, according to Carlson.
The market for retail miners has all but disappeared, he explained. The amount of power required to make a relevant amount of bitcoin has pretty much just left the larger operators who can run at scale using cheap power.
Calling large mining pools a "direct threat to bitcoins future", Carlson said that the community should be as much against the existence of several large mining entities as they are about one huge one.
He said:
Each and every investor, owner, entrepreneur or bitcoin enthusiast should be concerned that having two large pools and one 'Unknown' does not ensure the healthy future of the bitcoin ecosystem.
