Very interesting and accurate I think: Bitcoin Cash fair value based on transactions and other data is 1,900$. Right now is 400$ - https://www.coinfairvalue.com/
Just saying that the value of bch displayed on this site is inaccurate due to memo (same for iota & transaction spams not done by "users" of the money)
Thats like saying a news paper is not worth 25 cents because the paper only cost a nickel. The news printed on the paper is the value. The news printed on the blockchian is value.
