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.
True. I didn't consider this point. To provide with you income I assume your tokens would come from a premine. Premine should be OK in this corrupt swamp what cryptocurrency movement became.
