Bitfinex does not serve U.S. individuals and has not since 2017. On August 11, 2017 it announced it would stop verifying U.S. individuals immediately, stop letting them trade ERC-20 tokens, and discontinue all services to existing U.S. retail customers over the following 90 days, citing a verification backlog, difficulty providing dollar deposits and withdrawals for Americans, and the U.S. regulatory environment. Its terms of service have barred U.S. persons from opening accounts ever since.
New York is barred twice over. The February 2021 settlement with the New York attorney general required Bitfinex and Tether to stop all trading activity with any New York person or entity, in addition to the $18.5 million payment. Bitfinex holds no FinCEN registration and no state money transmitter licenses, and there is no U.S. affiliate; some large U.S. institutions have reportedly kept access under separate arrangements, which does nothing for a retail buyer.
Anytime Capital serves customers directly, in the United States and worldwide. Card, Apple Pay and Google Pay pricing starts from 4% with the spread included, cash is accepted at the Atlanta branch and by mail from any state, wires settle the same day, and the OTC desk handles size. There is a phone number, (470) 748-2530, and two offices you can visit. For an American who searched "Bitfinex USA" and found the 2017 notice, that is the practical answer.
