I think what we are seeing is pure FOMO where people are buying bitcoin purely to get their free segwit2z coins. Because the BCH fork went fine, they're treatin this as just another airdrop that they don't want to miss out on - even though this fork is very different, one chain aims to kill the other chain.
This is my fear. People are thinking it is like BCH, but at that time, there was replay protection, the addresses had different structure.
Now there's no replay protection, its the same addresses, hence its the same coin but on different chains. People will dump B2X in exchanges which support both coins and their BTC will de dumped altogether. Also coinbase will list it as BTC, and people will be buying B2X thinking its BTC.
Those who are not going to dump it will not lose their coins, but the price will be affected, as the massive dump of thousands of users will create a bear market and miners will lose money with it, as the difficulty will still be the same because theres no replay protection. Maybe the price will be even less than the costs for mining, which would affect China as well. Everbody will be affected, including the B2X guys, as their coin will be priced very low in relation to mining costs, turning their network slow.
Also there will be no lightning network, unless theres a complete change of POW where mining is turned irrelevant. B2X is a open attack on the network.
Exchanges should NOT list B2X as a separate coin until it have mandatory replay protection, as it happened with BCH.
So if they don't list it as a separate coin, what is the alternative? these scammers want to destroy the legacy chain. It must be measured in the market that B2X is refused and dumped into oblivion to crush the hopes of the forkers. Let's solve it in the market instead of the current nonsense of the hardforking corporations implying that everyone using Coinbase supports it. Let the market decide, otherwise Coinbase and co should be ready to face some serious lawsuits.
