So with 6K Nxt's will you recommend forging or leasing from your experience? I don't plan to make any transaction during this year. so I prefer the "lock and forget" method now, put it in a wallet and use nxt next year.

One of the very nice coins to follow with new features that are more simple and dynamic and will preserve the security of nxt users,
Whether to use smart token like ETH in myetherwallet

Awesomeness, that's how I'll describe the $NXT phenomenon over the past two days.  Did you all see the stalwartness of the $XVG price in this last correction?  12,500 Sats is our next stop.   

There's essentially two links between IOTA and Nxt.

One, the initial distribution for IOTA happened with two types of investment: 1) Direct BTC investment, and 2) Holders of the JINN token ( https://mynxt.info/asset/3061160746493230502 ) that was issued in the Nxt asset exchange, could swap their JINN for a participation in the IOTA project.

And two, Come-from-Beyond, IOTA core developer, has always been rumored to be an alter ego of BCNext, the original creator of Nxt who started the platform and transferred development to Jean-Luc, the current Nxt lead core developer who has been working on it since late 2013/early 2014. Recently David Sønstebø, founder of IOTA along with others including Come-from-Beyond, claimed in an interview that "before IOTA, we also invented full Proof of Stake through Nxt". That "we" is clearly out of place since David himself or other members of the IOTA foundation had no role in the invention of Nxt. Come-from-Beyond maybe was indeed the original developer of Nxt, although as far as I know he has not acknowledged that clearly nor provided proof so far.

Regardless, price of IOTA and NXT are independent.

Will Nxt price double in July?
The ignis is coming, and Nxt stakeholders are given ignis just for holding it.

It is said that the snapshot will be taken the quarter of 2017, I guess price will be increased a lot before that happen.

New to NXT... Can I Forge with the web wallet?

If not, and the network depends on forging in the Windows wallet... did creating a web wallet hurt the network?

You need a wallet with a synced blockchain to forge, from https://nxt.org/download

Creating a web wallet didn't help the network.
