I've been discussing with Nilli on the zennet IRC channel and there's been a couple points I thought could use some elaboration. I was a bit confused myself as to how a reaction from Coke and Disney would lead to a rise in value of the coins. Most of my confusion was due to me thinking of these coins as if they were any other crypto-currency, rather than as the artwork / collector's items that they really are (see the previous posts by HunterMinerCrafter and Nilli discussing the similarity to WotC/Wizards of the Coast and MtG/Magic the Gathering).
< stoopkid> nilli: you've said that in the event that coke/disney react to the coins (which i think is probably very likely to happen depending on how this goes), that the value of the coke/disney coins would rise; could you elaborate on how coke/disney's reaction would cause a rise in value?
< stoopkid> HMC_Alph: maybe you have some thoughts to that as well?

< nilli> As art controversy is the best thing for it
< nilli> as coins having the buzz all that matter
And it's really just as simple as that! If the remainder of the coins are burned after distribution is finished, the coins will be collector's items simply due to their scarcity, but in the event that Coke and Disney decide to react against the coins, then the coins will have far more desirability for collectors: from those just looking for more Coke/Disney memorabilia to those looking to have their hands on a piece of one of the great controversies of our time (not to mention that in the event that the coins do rise in value, people would seek to collect them just for that reason).
Btw Nilli thanks for mentioning Tau!
