Honestly i dont like any hardforks specially when it was resulted into new coin into existence. I think fork copycats is just after for easy money. Well thats my personal opinion about some forks, but if the fork was intended to upgrade for the better of the existing coin, thats fine and we should support it. In your list of Ethereum forks. i see it on CMC already that means those forks was already traded and also contributed in the entire CryptoMarketCap im sure the team behind those forks are already making money.
