$BTC Futures contracts in Bitcoin allow speculation on the future price of this cryptocurrency without the need to own it directly. To use them, you must first open an account on a platform that offers futures trading, such as Binance or CME. Then, choose the contract you want to trade, specifying the amount and the direction of your bet: long if you believe the price will go up, or short if you think it will go down. These contracts often include leverage, which can increase both profits and losses. It is essential to have a clear strategy and manage risk well, as the cryptocurrency market is highly volatile. Practicing with a demo account can be a good first step.
