Suppose the current price is $500 /BTC, and an investor buys a BTC at the current price with a principal of $500. At this time, investors can make 50 more BTC virtual contracts.
At this time, if the price of BTC rises to $750, an increase of 50%, the investor's contract income is 3.3333 BTCs. After selling at the current price, he can get $2,500, and the income is five times that of his principal investment.
Bitcoin futures provided by bitcoin exchanges are usually traded in bitcoin. Contrary to spot, spot is a real commodity that can be delivered by one hand, but futures is not a "commodity", but an agreement (contract) that promises to deliver the "commodity" (target) at some time in the future-a futures contract.
