Cryptocurrency exchange BitForex, which has not been heard from since it disappeared in February with about $57 million in user funds, announced on Wednesday that it would reopen withdrawals later that day, but two days later, users said they were still unable to withdraw their money. In a BitForex user Telegram group with more than 900 members, no one reported successful withdrawals, claiming to have experienced delays in "know your customer" verification requirements, problems with two-factor authentication and receiving confirmation texts, and a lack of response from customer support.
