I really dont understand how u made these assumptions. So u just calculate NEM market cap without even knowing what the NEM would be after development process is done. There is a significant possibility that NEM could be more usable in terms of a currency (distribution, POI, etc). And based upon your willingness to buy shares even before launch, i highly doubt that you have calculated very different valuation to the coin.
IMO it would fair to stop puplish these predictions, when the only purpose is to get cheap stakes and benefit on those.
I base my valuation for NEM using similar methods to other investors. Past history, fundamentals, competition etc.
Price discovery process for NEM has started and the market will decide in the end.
If I were offering fiat I would expect red flags to go up.
I am offering NXT for NEM.
Both NXT & NEM have huge potential.
