The Binance renewal mechanism mainly applies to contract trading and leveraged tokens, and does not involve general spot trading. The renewal fee is actually the funding rate, calculated every 8 hours, used to balance the forces of both long and short positions in the market. When the market is dominated by bulls, long positions pay fees to short positions, and vice versa. This fee is transferred between users, and the platform does not charge any fees from it. Understanding the renewal logic helps avoid peak periods or strategically adjust positions, reducing trading costs and enhancing long-term profit opportunities.
