That is money coming from the air, and it will crash at some point but no one knows when.
Do not move your money to Tether, do not even think about that because it can go to zero, and you will lose all your money.
Why has the supply increased by so much? Who is making the decision to increase the supply? It was just a 100 million a couple months ago. How is it 1.6 billion now? I am not bordered with the supply but i am always wondering why the coin stays at $1 most of the time or just move a little below it.
