Given that the rolled back chain will have the ticker $ETH, it’s prudent to rename the current one to $ETHNK, which I believe Supreme Leader Kim Jong Un will continue to run validators for.

So we will now have:

$ETH (the real Ethereum) $ETHNK (which Coinbase should delist immediately) $ETC (Ethereum Classic)

My Opinion: This perfectly illustrates the sad story behind centralized and controlled blockchains and the enormous difference between them and Bitcoin!
