Nxt looks cool and all, but I just don't get how it's going to work with the fixed transaction fee. If the value of Nxt rises to, say $1, That means the minimum fee for a transaction is $1! This implies a market cap of only 1 billion. How can Nxt be competitive vs other coins with such a high fee?
Otherwise, the PoS system looks really interesting. Can't we have PoS without fixed fess, or are fixed fees somehow fundamental to the PoS implementation (P2PCoin has the same issue)?
The transaction fee isn't set in stone. Here's a thread (including a poll) discussing various options for dealing with it in future:
https://nextcoin.org/index.php/topic,2075.0.htmlUltimately, the community will decide how transaction fees are handled. Right now it's set at 1 Nxt for simplicity, and this is ok for the moment because of Nxt's current low value.
The only solution in that thread that made any sense was the one about leaving the fee at 1 and using NXT as a "backbone" currency. I'm not sure how feasible this is.
the fee will actually be adjusted.
