I can send altcoins from an exchange correct? just not bitcoin?
Yes developers are going to allow exchange of selected coins. You can exchange every coin you want. Only dead or useless coins will be not listed.
It is obvious that developers would focus on introducing support for the most popular altcoins first.
I would be glad that they include every coin they used for their ICO: Bitcoin, Litecoin, Ripple, ETH/ETC, Maid, Dash, Waves, Doge.
We don't need another Yobit-like exchange with dozens of totally useless/dead coins.
