1. A contract is an agreement between a buyer and a seller to receive a certain amount of an asset at a specified price at a specified time in the future. A contract is a standardised contract between a buyer and a seller. The exchange specifies the type of commodity, the time of the transaction, the quantity and other standardised information. The contract represents the rights and obligations of the buyer and seller. In simple terms, it is an agreement to trade a certain amount of a commodity at a certain time and place in the future. (1) Futures Contracts A futures contract is, as the name suggests, an agreement to trade a certain amount of futures. By creating a standardised futures contract, a trading platform attracts more people to participate in it, while at the same time acting as a middleman to ensure that the futures contract is executed when it expires. We often hear the term 'futures contract trading', or 'contract trading', referring to the buying and selling of futures contracts on a trading platform. A futures contract is executed at expiry, but can be bought and sold several times before delivery, rather than having to hold it until delivery time. (2) The role of futures contracts Hedging future risk: This is often referred to as "hedging" or "hedging". For example, if the price of BTC rises, then the futures will lose money and the amount of BTC will become less, while the total value will remain the same; if the price of BTC falls, then the futures will earn money and the amount of BTC will become more, while the total value remains the same. Buy and sell futures contracts in the futures market that are of the same variety and quantity as the spot, but in the opposite direction. The profit in one market is used to cover the loss in the other market to hedge price risk. The price of futures is governed by a combination of spot prices and economic factors, and with the presence of a delivery mechanism, futures and spot prices are consistent in the long term. In addition to this, the availability of contracts makes it possible for prices to rise or fall unilaterally with an opposing force pushing prices back to a relatively ideal state, controlling spot market prices and bringing their short-term irrational prices back to rationality. Futures contracts have a leveraging effect: they can be used to amplify returns by making small gains. Of course, losses can also be magnified if judgement is wrong. (3) The way contracts are traded Contracts are traded in two ways, long (calls) and short (puts), and the existence of futures has added a shorting mechanism to the market. For example, if the price of Bitcoin is currently $10,000 and you feel that the price is going to fall, choose the corresponding leverage multiple to go short and sell the contract when the price falls to a certain level to make a profit. Opening long is the opposite of opening short.

The content introduced above is only about the basics of cryptocurrency, which is related to whether we can make money through cryptocurrency. Cryptocurrencies make money not only by scientific methods to increase income, but also by finding ways to save money. The handling fees are small, but they must not be ignored. I have calculated that with frequent transactions and long trading hours, the accumulation of fees can add up to more than 10,000 U a year. Next I will introduce a few common ways to reduce fees on large trading platforms. (1) Lowering Binance's fees Binance is currently the world's largest digital currency exchange, and you must sign up for Binance if you want to speculate on coins. The transaction fee is deducted from the assets received. For example, if you buy Ethereum/USDT, the fee is paid in Ethereum. If you sell Ethereum/USDT, the commission is paid in USDT. Example. You place an order for 10Ethereum at a price of USD3,452.55 per share. Transaction fee = 10Ethereum0.1% = 0.01Ethereum Or you place an order to sell 10Ethereum at 3,452.55 USDT per share. Transaction fee = (10Ethereum3,452.55USDT)*0.1% = 34.5255USDT What many people do not know is that the Binance transaction fee can also be reduced.

(2) Reducing OKX fees OKX is a professional digital currency trading platform loved by many users, and its transaction fees can be reduced. Depending on the volume of transactions, OKX divides its users into two levels: normal and professional. Ordinary users are graded according to their OKB positions, while professional users are graded according to their trading volume and asset size. The different tiers determine the trading fees for the next trading day. When calculating the fee levels, if the coin trading volume, total trading volume of delivery and perpetual contracts (USDT delivery contract, coin-based delivery contract, USDT perpetual contract, coin-based perpetual contract), option contract trading volume, and asset volume meet the conditions of different fee levels, users will enjoy the fee discount of the highest level. First method: OKX has an official maximum saving of 20%.
