1B tethers should be created when someone deposits $1B into Tether Corp's bank account. "Created out of thin air" means tethers have been issued on blockchain, but no one deposited any US dollars into said bank account. What evidence do you have for the latter? If you are confident that is exactly what happened, why don't you go and short USDT/USD pair? Why no insider executed that profitable short trade? How come after so many years of tireless accusations on every message board available, that 99% of people seem to agree with, said pair still trades at exact 1.000 ratio? Why authorities have not stopped the obvious fraud going on for so long? Something doesn't add up.
