No, saying Blizzard buys it is a lie. They point-blank say it may take several days to sell depending on market activity. Blizzard doesn’t guarantee or buy anything.
Dunno about the when but the amount remains the same no matter the when. It will always be sold for what it was listed for at the time you posted regardless of what it is when it actually sells.
This does mean that the economy either eats or creates the difference in value.
The onus is on you to provide direct evidence to the contrary. You don’t get to just say things along the lines of “Blizzard is lying” without evidence.
Going by the overview video, the fine print while listing a token says “Estimated Time to Sell.” As in, a prediction based on how long the selling queue is and how quickly they’re being bought, to give the seller an idea of when they might get their gold.
The overview also confirms that the amount you’ll get for the sale is locked in at the time of listing.
Because the rate people have been buying them and the rate people have been selling them has evened out over the years.
When the Token was new, the market for them swung much more wildly, there were periods where the thing shut down because there were 0 tokens for sale, which were usually followed by periods where people would wait 2-3 days for their listing to sell because people flooded the market once the “demand” pushed the value high enough.
This still happens, particularly during very low in-game activity periods where a Shop sale occurs. It’s happened a couple times throughout DF where you’d open up the AH to buy a token and receive an error saying there were none to buy.
The claim that it never takes less than two or more than 12 hours to sell is entirely false.
