Newbie interested in decentralized markets

[Geneko]

The reason I post here is obvious since this is my first post on bitcointalk.
 
I am looking for giveaway for Nxt, my favorite among similar projects like Bitshare and Mastercoin.
I have made my homework for giveaway and need to present it.
In a mid time anyone familiar with how exactly those markets should look and work I would appreciate some further information’s.

Also I would appreciate some tips. My Nxt account is 13982455833858333697

Thanks in advance
