Why a secret network has few exchanges?

Why a secret network has few exchanges ?

Wouldn’t it be important for the secret to be added in several changes to give visibility?

We only have 3 exchanges available. (BINANCE, HOTBIT and ATOMARS )

Add Coinspot to that list. So in Australia that is the big one for new players.
Very user friendly for FIAT to Crypto exchange.
Maybe not so much about the quantity but the quality
For us Binance & Coinspot would be the top 2 for different reasons
