Buyer buys a software token. He gets what he buys on that day same as any other owner of tokens selling his copy of the software, not future promises. A free market.
Is it the same model that David and CfB did with IOTA, labelling the token as a software?
Ostensibly IOTA sold future promises, a timeline, etc. Afaik, the IOTA blockchain software wasn't even running live when they sold tokens. Afaik, it wasn't even possible transfer tokens to another party for some time until after tokens were sold.
Also afaik, there is no distribution of IOTA other than tokens sold.
Most of the tokens will be distributed, not sold, because there will be an ongoing (perpetual) distribution (but also eventually perpetual monetary deflation...are you confused yet, lol). But there is going to be something very special about the way the distribution works, which I think will be very enticing for everyone (to those who purchased some tokens on an exchange and to those who are receiving the distribution).
You will not be able to get a lot of distributed coins without doing significant work (or paying someone to for you). In essence my distribution scheme is a "proof of work" but not a computational Proof-of-work.
