This is the question you all should be asking, because although there is nothing better than "free" when it comes to most things, the reality of it just isn't possible.
All people are innately greedy, and without the "what's in it for me" factor, I have a very difficult time understanding how IOTA will be successful.
Someone has to maintain the infrastructure, someone has to pay the electric bills, someone has to man the helm, and all of these things cost money, so without it... how will all of this be paid for?
Also, do we really understand tangle enough for such an enormous valuation?
I remember not too long ago, a university easily hacked and pointed out all of the security flaws within the IOTA software, so is this something we should value so highly?
Oh, and don't forget the whole centralization argument with IOTA either, because the reason why the great majority of us do love blockchain technologies, is due to its decentralized nature.
What say you guys and gals, is IOTA here to stay, or is it just a fad?
Or is it too early to tell?
