Warning:
CoinMarket.io and its developers use only one account on bitcointalk - which is named coinmarket.io
People who PM you and claim to be from coinmarket.io are scammers.
Some of them are trying to collect bounties from "getting coins listed".
In any case, be aware of this

So, Templar. Did you contacted with the real admin?
I received a PM similar to the one that guy describes so probably it wasn't the real admin then...., but I understood he would list it first and then I pay, so I don't know how he would have tried to scam me.
I contacted him again and told him I'm ready to pay. Let's see his reponse.
Probably he is reading this so he won't respond...
