You seems to be very Naive. In what part of your normal mind says that you be able to sell few hundred of sugar for profit?
Universa itself is registered as a user for sugar platform by the definition itself universa will be actively be able to buy and sell at the exchange. Which by definition has an agreement to hold 100k T of sugar at its disposal. Which might makes you wonder if you really got a chance to take your profits for few hundred of sugar before they empty theirs stocks before handing out profits for you?
I see, and It makes sense. But what if someone simply wants to speculate on the price of sugar? No need for delivery then. I buy a few hundred kilos today, sell them tomorrow for profit. I know that either way your share of sugar is tied to a physical amount, but I think the majority of people interested in Digital Sugar are there to speculate: if they were interested in buying tons of sugar, they would use other channels. If you invest in oil or gold you don't want actuals barrels or ingots, no? Again, I might be wrong, that's just my take on the whole affair
