I just remembered that there was an specific project (Augur?) with alt-coins that intended to make a platform for "prediction markets".
A market is, in essence, just a group of people (or robots) buying and selling things. This can be physical goods as in a grocery store, services as in Uber, or financial assets as in the stock market.
I wonder if any of you has had any experience using the platform or the token and how the results may vary depending on the general alt-coin market, that is, even if winning a bet will actually give you a decent result if the value of the coin drops in that market cycle.
