For the first time, Tether holders are actually redeeming Tether for actual $$$. Tether has fallen 9% in market cap over the last 4 days. $6.5 billion dollars have been pulled out in a controlled way, in fractions every 12-24 hours. The question is when Tether runs out of actual $$$. If it is after like ~$20 billion withdrawn, we are looking at losses of ~$50 billion. And it could take Bitcoin with it.

[edit] $8 billion down now.
