Earlier quoted context omitted.
> When you go to withdraw from Tethers it basically says "if you don't have more than $50k in claims, go away" [1]. Suffice it to say that most of their customers don't have that. This is not how most people redeem tether, they go to any of a wide range of exchanges (kraken, poloniex, bittrex, etc) and trade whatever amount (from a dollar or whatever the minimum trade amount is).
How does that prove that Tethers has USD to back each USDT? If it's all exchange-based then there's no guarantee of a peg to USD.
However I don't think it's obvious that this thing will implode, based on the information we have we can only speculate. Pointing to screenshots about being unable to withtdraw tethers is a red herring and has nothing to do with whether tether will implode.
