There are Excellent coins that fail and some inferior ones that get publicity. It is marketing, advertising, spreading the word about your existence.
That is where Hush and BTCH are far behind.
e.g.
Coinomi supports all Bitcoin forks, but BTCH is not there.
CoinDar.org lists Events and news related to altcoins. Nothing about Hush or BTCH (except the airdrop)
There is no mobile wallet for either Hush or BTCH.
No website for BTCH not as far as I know (Only single page about the airdrop)
BTCH is not listed on any exchange.
No chinese version of the Hush site. No korean one either. (The most altcoin fans)

I beleive Hush and BTCH have growth potential, but without strong marketing little can be acheived.
