the nxt asset exchange is not in the best place right now. a lot of assets are losing value due to the 2.0 proposal. unless you can convince nxt holders that their return will be greater than what they expect from 2.0, i don't believe you will be able to raise significant amounts of funds there. if you want to issue an asset do it via http://nxtcrowd.fund/. its a centralized gateway for nxt assets to tap into btc liquidity. you'd probably have to contact coinomat on the nxtforum.
