My opinion is that Nxt adoption in electronic commerce is still very low. That probably will not change until the main projects of the technology tree are implemented (smart contracts etc.) and the wallet can "stabilize", so merchants would not to have to update every month or so.
Long term I'm optimistic, but I don't expect to NXT to rise fastly in the next months.
Getting Merchants to accept Bitcoin is difficult enough , adopting an alt currency that no one has heard of is a whole new level of difficulty. Most merchants think that it isn't worth their time integrating Bitcoin for the potential 400k- 1 million Bitcoin regular users(not total investors). NxT users are far more speculative than Bitcoin right now thus there may only be a handful of potential clients willing to spend NxT worldwide.
