I feel you phil.
But; I also see it this way...
Let people drop off the GPU side; and we will see more instances like our Skien days.... Everyone was heavy on asics..... either asics or ETH for the most part.
I see the exact same happening in the future; just; a different piece of hardware and manufacturer now.... as well as different algo.
I still must admit:
Each device has it's place.... (good or bad)
But when you consider the ramifications of the devices when compared to each other; yes; asics secure BTC; but, they secure BTC... Each different algo has seemed to bring along its own waves of differences in effects on all other devices and strategies. Just because a powerful device worked for one scenario; doesn't mean its a good idea for the current scenarios.
If these companies; designed the devices to only make a modest profit; we would have a winning company/device to support in my eyes... the problem would be severely lessened.... to a point... a dull point.
I wont ever buy a brand new piece of shitmain gear. Never. They are a crooked company and don't deserve it in my mind. I hope many people do the same. They got excessively greedy; look at the profit margins that can be deduced. It's insanity.
I hope we find a way to change the meta of POW mining..... level the playing field and try to keep this thing from getting out of control and 100% centralized; which is my ultimate worst fear.
Powerful devices further the divide between the "decentralized and attainable by the layman"; and "big fish that can afford to dump on the latest and greatest to reap the second best rewards (first best being the manufacturer). How can we change this?
