CEX also has its era of relying on big names: Bitfinex is now at the main table this year. Many people still have the impression of Bitfinex (Green Leaf) as an old-school, hardcore exchange. But in 2026, you need to have a new understanding: Bitfinex is no longer just a simple exchange; it is a digital Federal Reserve branch disguised as an exchange. While all CEXs are still struggling over tiny transaction fees, Bitfinex directly announces: long-term zero fees ($0 Fees). Yes, the Maker and Taker fees for spot, leverage, and contracts have all dropped to $0. ❚ Why doesn’t it need to charge you fees? Many people are curious: with all lines at $0 fees, how does Bitfinex make a profit? 1/ A terrifying profit engine: Tether (USDT) Integrated structure: Bitfinex and Tether's parent company are both iFinex.

Although trading is free, it offers the most mature P2P lending market in the industry. It charges lenders a service fee of 15% to 18% of the earnings. The hotter the trading and the higher the leverage demand, the thicker the commission Bitfinex receives. ❚ In terms of data: asset security is the ultimate trump card. BTC reserves: Holding over 410,000 BTC, ranking third globally. This level of reserves represents extreme redemption capability and market pricing power. Ultra-fast engine: Matching delays as low as 4 milliseconds. It is also the oldest exchange since Bitcoin's emergence in 2012, a safe haven trusted by institutional investors....
