I requested a withdrawal which was approved at 21-06-17 02:36:36(JST) or 17 hours ago. Bitfinex promises to process bitcoin withdrawal within 12 hours and now apparently they failed to keep their promise. I have emailed support@bitfinex.com and still waiting for reply here. I need to return some borrowed bitcoins and I am forced to break my own promise too. very disappointed. The amount was 45.73895428 BTC
hopefully this gets resolved.
