No, the 8MB blocksize is not the only difference......
Bitcoin Cash also has the advantage of having fired Core. Who needs developers? Instead, they have a clique of promoters who lack sufficient credibility to sell used cars, but do have plenty of money to manipulate the market and prop up their pet scamcoin. Also, they have
the domain name bitcoin.comwhich never had anything to do with Bitcoin, according to Satoshi.
But to me, the most important feature of Bitcoin Cash is
centralization. The network is safely under control of a nanny named Roger Ver (or more likely, his handlers). Why, its comfy as a padded playpen!......
Maybe. But centralization is a direct result of ASIC, first and foremost.
Bitcoin has sufficient real world problems, it may not be helpful to argue against alternatives.
Perhaps better to attempt to understand them, their various advantages and disadvantages.
