I see some discussions regarding exch adding new coins in BTT.
I think this discussing would fit better here, as this is an altcoin forum. Do you miss any coin in exch.cx?
Personally, i got support for all coins I need right now.
It's the same for me, the site support all the coins I need.
However, I think people are more interested with adding new networks (especially for stablecoins) than new tokens or coins. Personally I don't care, ETH isn't that expensive to use at the moment, and I appreciate that eXch doesn't list just any blockchain, and that they apply a very strict selection (as users we benefit of the security, stability etc..etc... required). They regularly explain why they refuse to add this or that blockchain, and they seem to know exactly what they want.
