Is something called 'tether' being used to prop up bitcoin while sharps bail?

Interesting read. It's hard for me to imagine that a) they really have $1.7B in hard cash reserves and b) that anyone would invest money in a blockchain vehicle whose value is tied to the USD, when they could just own USD. Smells very ponzi-ish, and that ponzi could be what's propping up BTC at $10-$11k.
