Should we launch the decentralized exchange now or wait when we get more coins distributed? I don't want Nxt to become an instrument for elite businessmen only, coz only rich ones could afford buying 1000 NXT to issue an asset, or 100 NXT to place/cancel 100 trade orders...
I think the real question is, can you get the stakeholders to distribute more coins?
If more coins to be distributed (especially from the so far idle accounts) in the next few days, weeks, then I think you should wait a bit with the exchange. If not, and there is no communication between the stakeholders, (or some simply not willing), then there is nothing really to wait for, launch the exchange.
IMHO.
