Seems the last 100 million tether just arrived at Bitfinex account at 10:00 UTC 21 January and see it the price jupedfrom 11600 to 12200, it costed 30 million.
The rest 60 million is still on way and most possibly will be pumped in if price will fall below 11 000 or they will HODL for the worst case - price below 10 000.
I think this time they will lose
