Yes an increase in utility increases use cases. This in turn increases demand, which increases value. Also, increased dust affects fees, more dust higher the fees, this will affect value as well. These changes could be nearly negligible, but technically, yes it affects value.
I did not take this into account. All those input scripts into an address means a bigger transaction fee ( if ever redeemed ). Thanks for your thoughts.
You don't have to spend the dust input when deciding to redeem your coin, you can just let it sit there and be done with it, no affect on fees whatsoever.
If given the choice between a coin with and one without dust, I would prefer without.. but I hardly see a negative price effect on a dusted coin. Especially true of the rarest few.. for example all the 1000BTC coins have all been dusted, but I'd still love to have one
Would have to agree with this one right here, if given the choice between two similar, same priced coins with one having dust added and one being at face value,
I would opt for the face value coin. It's a question of preference, nothing more.
However, I don't think it would or should change the price of either of the coins when being sold. It's just a question of what I would prefer (Not that there's not the possibility of it being dusted later anyway).
