I have one GPU. I don’t have a big stake in the mining game. I’m actually in favor of proof of stake in most cases.
What I want to avoid is another takeover of a cryptocurrency by Bitmain.
They have done enormous damage to Bticoin recently. They created Bticoin Cash and tried to pump it past Bitcoin’s price. They threatened to create a contentious hard fork with no replay protection. They spammed the mempool and forced users to pay outrageous transaction fees. This crippled the network and caused many retailers to stop accepting Bitcoin indefinitely.
I would love to see Bitcoin’s proof of work algorithm be changed as well. ASICs and centralized mining are cancerous to cryptocurency.
