The transaction fee types for cryptocurrency trading on #交易手续费揭秘 are diverse and influenced by factors such as platform type, trading pairs, and user levels. The specifics are as follows:

• Transaction Fee: This is the primary type of fee, divided into 'Maker' fees and 'Taker' fees. Makers increase market liquidity, with lower fees typically ranging from 0-0.2%; Takers eliminate market liquidity, with higher fees that can reach 0.5% or more. Some exchanges adopt a tiered system, where larger trading volumes lead to lower fees.

• Deposit and Withdrawal Fees: Most exchanges do not charge deposit fees for cryptocurrencies, but fiat currency deposits may incur fees depending on the payment method (such as credit cards). Withdrawal fees vary based on the platform, payment method, and cryptocurrency type, with Bitcoin and similar currencies typically having higher withdrawal fees due to network characteristics.

• Spread Fees: This is reflected in the buy-sell price difference of cryptocurrencies. A widening spread means a higher buying price and a lower selling price, which can reduce potential profit margins and can be seen as implicit trading costs.

• Funding Rate: Mainly found in perpetual contract trading, this fee is based on the price difference between the perpetual contract market price and the spot price, paid to long or short traders and settled every 8 hours, fluctuating according to the capital amounts of both sides.

• Other Fees: These include account maintenance fees, idle fees, margin trading interest, and fees for special trading features (such as stop-loss orders), but not all exchanges charge these fees.

There is a significant variance in fee standards among different exchanges. For example, Binance's spot trading fee is 0.1%, which can be reduced to a minimum of 0.075% when paid with BNB, while contract trading fees generally range from 0.01% to 0.04%. On OKEx, the taker fee for ordinary users is 0.06%-0.08%, and the maker fee is 0.06%-0.1%.
