Why are two exchanges not enough for the moment?
Because they are very small and mostly known by folks that know NXT. If we want the mainstream people to join, than either bter or cryptsy is a must.
Yes, bter is a must to attract Chinese investors. All the coins have gained a lot in number of investors and in price after listing on bter.
I just bought 1 million NAS @ 17 satoshis. Welcome me.
Exactely this is the reasoning behind this. Most initial stakeholders seem to be chinese, I doubt they want to use an american exchange to trade. Bter is very nice because they will likely add a NAS/CNY market also.
