$BTC When you invest in futures trading, you do not need to buy or sell the actual coins. Instead, you buy contracts that will be settled based on the future value of the coins.
Suppose you want to engage in futures trading with Bitcoin and you have dollars in your account, then you can buy Bitcoin futures contracts. When the contract date arrives, you will realize a profit or loss based on the value of the coins, but you do not need to buy or sell the actual coins.
In futures trading, profits or losses will be settled in dollars in your account. You will not receive delivery of the coins, but your dollar balance will change.
