It was on Thursday that the Hong Kong-based crypto exchange Bitfinex announced on Twitter that they stopped all crypto trading.
The reason for the stop was stated to be that they are undergoing “unscheduled maintenance” of the exchange.
We are undergoing unscheduled maintenance with trading temporarily halted. All wallets remain unaffected and all traders will be kept informed of updates as and when they are available. Thank you for your patience.
