#预测市场 $BTC I feel this is basically an evolved version of event contracts, since the odds change with the price. From my experience, it offers the best value when you play at 9:30, when the U.S. stock market opens.
Because the price moves so quickly, correctly guessing a reversal point can be worth several rounds of event contracts. Another perk is that you can play with as little as $1, and there are no fees!
