If you are taking it as received mistakenly from someone, think once again because the fee would be many times the USDT received by you. I think it was a dusting attack or some rebates for trading if you were involved in trading some coin where some competition was going on?
Yeah, upon checking the above post, it is confirmed that it was a dust attack although it doesn't make much sense. There's nothing to think for me as the wallet belongs to Binance and I don't have to pay anything for that.
I think there is enough discussion and I got the reason. Locking thread to prevent unnecessary reponses.
