True, but BTC2 is still listed in 3 other exchanges that do work so the next step, unless something changes significantly, is to upgrade rather than add an option. There's some steps being taken behind the scenes towards a fiat gateway which leads me to think that it could come before another traditional exchange listing, and a higher tier exchange listing is of course aimed for as well. However we're not planning to negotiate for a hasty listing in another mediocre exchange.
I've been following the project since the very beginning and I admire the excellent work of the developers and the team!
