If you haven't been following along, here's why this matters: Tethers is a sole-source cryptocurrency, pegged to the US dollar. Bitfinex produces it, though they're cagey (some would say outright lying at times) about the level of involvement. The primary purpose of tethers is money laundering, even more so than cryptocurrency generally. Bitfinex was cut off from the US financial system, which makes it impossible for…
Tether certainly has a connection to Finex but they are not its biggest client. Tether is being used by crypto-only exchanges mainly Bittrex and Poloniex to give people the possibility to trade coin/usd.
A possible explanation of Tether growth is simply that: Polo and Bittrex started using them. Is that shady and tries to avoid regulation by placing a crypto sign over a real dollar? Yes.

Except that the price of bitcoin in finex has been lower than other exchanges in the last few weeks and only slightly higher now.
