At some point someone will try to cash out on the tether. And that's when we'll find out if Bitfinex really has the USD reserves to back that as they say they have.
But it's getting harder and harder to believe that money really exists.
Tether keeps getting printed by the millions specially when bitcoin is on a downtrend (just today 200M was printed). For some reason I doubt someone wrote them a check for 200M USD today.
Also Bitfinex never completed or released audits they promised.
The more you dig the more it looks like Bitfinex is printing fake money to pump cryptocoins.
I wish that a reputable company or YC startup would do exactly the same thing but in a very legitamate way.
It seems like they could make a good amount of money by charging withdrawal and transfer fees.
