I exchanged USDT to BTC. A small amount just to test the service. I did not find a lot of info about your exchanger so I am not sure I can exchange large amounts. Your exchange rate is good tho. I'll try to make another exchange on a slightly bigger amount and write here about the results so everyone will see if your exchanger is safe. I also see that you are about to be listed on BestChange so it is a good sign, they don't list scam services.
