Your assessment of the decentralized mining is completely wrong. While I agree that bitcoin classic is too centralized, especially in low-energy cost countries. Bitcoin cash strikes the best balance and another fork of the bitcoin chain should not be advices. Also we do need big miners behind the currency so non technology investors will participate.
Tl;dr thank you but no thank you
Unfortunately, big miners screwed bitcoin mining decentralization. Small miners like me cannot compete and will be forced to use expensive equipment like Antminers just to keep up.
In fact, Bitcoin Cash mining is even more centralized than Ethereum mining.
Experimenting with this BTG. If this works out to be very profitable, Ethereum miners like me can shift to BTG.
