Bitfinex、全市場商品の取引手数料を撤廃

The evidence provided strongly supports the truthfulness of the statement. All sources are primary and from the authoritative source, Bitfinex, ensuring high credibility. There is a high degree of consistency across all provided materials.Multiple official announcements, including blog posts, press releases, and a dedicated landing page, uniformly declare the introduction of a zero-fee trading policy. The most compelling evidence is the dedicated landing page for the policy, which explicitly states that zero fees apply across a comprehensive list of its markets: "spot, margin, derivatives, securities, and OTC markets." This directly addresses and supports the claim that the policy covers "all of its market products."Furthermore, the policy is presented as being applicable to "all customers" without tiers or volume requirements, reinforcing its broad and encompassing nature. The existence of an official fee schedule page, while not detailed in the summary, serves as the definitive source for the policy, and its presence alongside numerous clear announcements adds to the confidence that the policy is officially in effect. There are no contradictions in the evidence provided. While absolute statements like "all" always carry a small risk of having unstated exceptions, the provided sources are unequivocal and broad in their claims, making the statement highly likely to be true.
