Is it worth to buy their own coin which they only do exchange.?
example : Binance exchange. their coin is Binance coin (BNB)
probably they have a lot stage on ICO and maybe this is their 1st stage (exchange)
I just want to know your opinion only.
It's worth it if you are frequently trading,since usually these altcoins created by exchanges are here to make trading fees smaller.
Exemple:Binance,there is an option to make trading fees only 0.5$ if you pay them using BNB.
