  "textContent": "Effect on probabilities is the same, but the way you think about it and the cashflow for you is different. This is a play money market, so we do not reserve money in your account when you short sell (that is when you sell the asset that you do not own yet) but we pay the money to you immediately when you sell. And, if the event did not happen in the end (so you were right selling it) then you keep the money you’ve got. But it you were wrong, and the event did happen, then you’ll have to buy all the shares you owe (the number of shares you short sold) for the price of 1.00 each, that is you’ll then pay more than you initially received. Short selling is a bit confusing subject",
