Now, that IPO type model (which will also be Etherium I believe) isn't necessarily a scam just because it breaks accepted "rules".
Selling shares of a new tech to the market at whatever price the market will bear, is not scamming. I don't have any evidence that NXT is scamming anyone. I have also sold shares of my companies to the public.
What I don't believe is that these things will become currency. At least my shares have never succeeded on that
Your last point is something I've really been wondering about and I think I've posted it before. Something to consider - We could probably use IBM stock, etc. like a currency (theoretically) and if you remember, look at some of the older notes before central banks got involved. They were stock issued by companies (or something akin to that). There were a variety of them. Even Bitcoin is considered a property by the IRS (so far).
Anyway, this is an interesting unknown and even though I'm leaning (barely) towards what you are saying, the conundrum is we can't know as we will decide. Hope that made sense.
People inherently like to barter and trade things. Kids "due" it with their Pokemon cards and such. And it never really stops, though we seem "forced" to use State controlled fiat money.
So, I am very open to the possibility of NXT, Ether, etc. also being used as a money. There are an awful lot of them - perhaps they will replace Doge. LOL
And bigger yet, this is going to further change our understanding of what money is.
Let the disruptions begin...
Its about sharing
