Hello. Something weird is happening. I have sent 1 USDT to an external wallet. That USDT was sent successfully at 21:04 hs, then later I received 1 USDT in each case at 21:05, 21:06 and 21:07. So my balance of USDT went from 501 to 503. ( I also see that trezor charged me with the fee of 1.89 dollars for the transaction , ( which is okay ) )
Later, I sent again 1 USDT to a different external wallet at 22:00. The USDT was sent, I can even see the token in that wallet, and again, I received 1 USDT from the sane wakket one minute after. I also see that the fee was charged ( which is okay )
So now i have more USDT that before ( I had 501 and now I have 503 )
Also I realize that the usdt that are coming in, come from my ETH wallet. ( my ETH wallet in trezor ).
Why is that?
