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)
but Memo is a valuable resources, it is freedom of speech. Memo is a very important feauture of BCH blockchain in my opinion.
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.
