Ongoing crash/healthy correction showed that bitfinex has a serious amount of cash that is backing up tether. Did they have that money to begin with as they were printing tether or did they simply cashed out the bitcoins they bought with non-backed Tether and acquired a massive fortune from thin air is another question. I have no doubt that they are pulling of some serious questionable tricks. Yet as long as tether is not fast crashing to zero I am not worried at all. and if it has not crashed as the people were panic selling tether just a week ago or so I do not think it will ever. Unless they go crazy reckless.
