This one wallet bought 32,000 Bitcoins yesterday
Well just before the major dump 200 million tether were printed. I'm guessing a whale cashed out up high and now he thinks the dip is over so he's buying back in.
Tether are created when people sell crypto as well as when people want an on ramp on to crytpo. Considering the price drop after that they creation weeks ago im guessing the whale wanted to protect himself and buy the dip
