Live chat: help-center article "Bitfinex customer support" describes a 24/7 pop-up Live Chat on every page. listed_coins left null: features page says "Bitcoin, Ether, Solana, Tether and 250 other currencies" while pub:list:currency returns 254 symbols incl. test/derivative/fiat entries (~130 spot crypto) — no clean official figure. Proof of reserves left null: only a 2022 commitment (Antani/Ballot) is published, no periodic report found. listed_coins = 250 from the features page wording "Bitcoin, Ether, Solana, Tether and 250 other currencies" (marketing figure, not an API count). proof_of_reserves = true per the margin-lending page ("Regular proof-of-reserves") and the 2022 transparency blog post; no published PoR dashboard URL was found. USDT withdrawal fee from the official Fees page (Withdrawal fees table): USDt (Tron) FREE = 0 USDT on TRC20; USDt (ETH) 2.1479 USDt; USDt (SOL) 0.5.
