I don't really understand why they'd be removing coins at this point. If I were them I'd be trying to add support for as many coins as possible to compete with cryptsy, coinex .. etc.
It's called dilution. If you have all these shitty coins on your exchange, no one is going to take you seriously.
Good riddance to both coins I say. Nothing of value was lost.
I haven't even heard of anyone MENTION TRC in awhile. FTC though, there's gonna be tears
