#交易类型入门 The cryptocurrency trading types are diverse, suitable for different investor needs. Spot trading is the most basic method, directly buying and selling cryptocurrencies (like BTC/USDT), suitable for long-term holding or short-term operations. Contract trading supports leveraged gains but carries higher risks, divided into perpetual contracts and fixed-term contracts, with a need to be aware of liquidation risks. Options trading gives buyers the right to buy or sell in the future, suitable for hedging risks or speculation. OTC (over-the-counter) trading is conducted through intermediary platforms for large fiat currency exchanges, offering stronger privacy. Additionally, grid trading uses automated strategies to buy low and sell high, suitable for volatile markets. Beginners are advised to start with spot trading, gradually learn risk management, and then try more complex trades. Be sure to do your homework before entering the market and invest cautiously!
