you need to be a lot clearer about that! what you said here doesn't make any sense and the only information that i could find about "Reverse Bitcoin Hardfork" is a GoldCoin related thing (link:
https://www.goldcoin.org/fork_faq.html) where since it is a copy of bitcoin they are basically pulling changes from bitcoin to their own fork and adding them there which has nothing to do with bitcoin.
That's what I'm talking about. The medium article on that page says that the new chain will be the official chain?!?

well that has nothing to do with bitcoin and i don't see the connection between that and CW!
GoldCoin will have a hard fork where they add a lot of new features which they copy from another project (in this case from bitcoin) then the new chain after the fork is going to be the official GoldCoin chain! as it is with any fork.
that medium article is intentionally using certain terminology and is advertising it in a way to hype their altcoin up but in the end it is still an altcoin that is copying bitcoin code. there are at least 50 of them that have done the exact same thing from the most popular one LTC and BCH down to less known ones like BTX.
