Nxt is going to make the scalibility better and the possibilty for companies to make their own blockchain on Nxt 2.0. This is what will be a key feature for blockchains the coming years.
When you hold NXT from 1 july till 1 october snapshot are taken and you will receive the same amunt in the forging/staking token for Nxt 2.0: FXT (temp name). You will receive all the fees from all the blocks you have forged of all childchains! Something like mining, but you can do it with your own computer.
And you will receive 0.5 FNX (temp name). The transaction token/coin in the new childchain for the new Nxt.
And you keep the NXT in the old Nxt that will not stop. So good give you nice profits the coming years.
Soon the marketing campaign will start and probably people want to buy more NXT. The price of NXT is low now, so could be a good choice to do it now. It's very unlikey that the price of NXT will be lower (never did before).
And It 's cool to be part of Nxt of course!
So, as a Nxt holder (as per July - October snapshot) I'd receive Nxt 2.0: FXT equivalent to my original Nxt holding plus I continue to own that original holding as well - i.e. it's not a swap?
You are right. It is not a swap, because you don't need to send your original Nxt to exchange for new Nxt 2.0.
