BTC-Arbs doesn't have all BTC because he was hacked. So the payments is going to be slow because he is paying us with arbitrage profit. So it may take half year to pay us all back. Maybe more. According to the estimate I made when BTC-Arbs was paying us through the legacy system it was going to take a year. So if he try to pay faster than that not everybody will receive a full refund. I hope he is not doing anything unsustainable. I wish I would have real numbers of BTC owed and BTC lost.
