nothing happens!! I do not trust tether or Bitfinex but this is a conspiracy of the US and the banks to control the cryptocurrency !! I can say that nothing succeeds even if they close "tether", there will be another "tether" that will do the same thing that makes tether !! there will be a "petro" around and there will be a "bitusdt", or another cryptoRublo or cryptoYuan somewhere in the blokchain and so that goes the world to us being human we do not like being controlled we like being free !!
