So when all is said and done BitCoin core will prevail as it set the initial rules of crypto as far as we know by introducing the blockchain.  As long as any crypto uses any blockchain it just means it has different rules. Core is the best word to call BitCoin and until there is a %51 percent consensus all hard forks are just alts fueled by greed until another fork brings the alt back into the original chain or the alt dies... Or at least will never be worth as much. The name BitCoin remains forever in the cryptocurrency market.
