I've been following this with some interest..until now. That statement is just...well...mind numbing regarding the valuation.
$1500 to $2M in 6 months just isn't going to happen, you have some sound idea's, and the concept is interesting, but there is nothing here that gives Nxt the potential for an investment increase of 2666% per annum in the first year...nothing.
Your presented 3 USP's are not particularly unique either, other cryptos offer similar, but at a very strong risk of sounding coy and brash (which I don't like doing), until you have a feature set that rivals the following, it's game over before you start..I'll start with similar to the ones you list:
1] Efficient electricity usage
2] Multiple in system exchangeable currency support (kind of "colored" coins I guess)
3] Instant TRUSTWORTHY transactions < 10s
4] Secure wallets
5] Encrypted transactions
6] 100% anonymity
7] 51% resilient
8] Sybil attack resilient
9] Self governing dynamic supply model and distribution
10] REAL Currency value stability
11] TRUE Peer 2 Peer exchange and marketplace
12] Transaction notes & messages
13] Secure encrypted "email" w/ encrypted attachments
14] Invoices, remittances and receipts sub-system
15] System based escrow
16] Ratings & rep system with community dispute/resolution model
17] Ready to go payments API for eCommerce
18] POS terminal support
19] Scalable to VISA scale (read 300 trillion transactions per year)
20] ..... I'll stop there I think
I could go on and on, but I've proved the point, that is, $1500 - $2M in 6 months would be a stretch for a system THAT advanced even with a huge marketing push...and a system that advanced is coming. The above is a fraction of the eMunie feature set, ALL and every part of it decentralized and it will be on a device near you this side of Xmas.
Enjoy playing on the railroad until the freight train cometh.
I can not give you exact numbers. Try to assess them taking into account some facts:
1] Nxt does not require to waste electricity (no centralization of mining power around pro-miners)
2] Colored coins will lead to a revolution in finances (decentralized exchange of property in atomic transactions)
3] Instant transactions (I can't find words to explain how it's cool)
Nxt collected 1,500 USD worth bitcoins. I'll eat my hat if in half a year they won't be worth a couple of millions.
