It gives you the chance to win 1 USDT with 1 BTC.
OP, this project look promising to say the least. Must be very profitable for you if it works.
But why do you think anyone
would risk 1 BTC in order to have the chance to win 1 USDT? I don't understand this part very well.
Op made a mistake there, it's other way around. If you click the telegram link given in op, it says, "@OneUsdtTo1BtcBot".
