Does your platform provide trading of these tokens or you just add them on the market?
This website is a clone of ForkDelta/EtherDelta. They utilize EtherDelta's decentralized contract which costs nothing to add a token but are charging 0.2 ETH to "request a token to be listed"; So, there is nothing free in their website and
they are trying to scam the users by charging ~$55 for something that is free.Also, how broke are you that you couldn't afford a cheap hosting and a domain name? Why would you host your site on GH-pages? If your websites involve any transactions, I wouldn't touch it with a 10-foot pole.
It has nothing to do with being broke. The website is hosted on GitHub, so using GH pages is more like a "transparent" way of showing that the website is running the same code as shown in the GH source repo.
Still, this is nothing more than a clone of ForkDelta/EtherDelta. There are no reasons why you should use this website instead of the original ones (besides the extra 0.2 ETH they are charging you... LOL).
