You have probably violated the terms and conditions of the 1xbit site. I really can't imagine anything else. This site has had major problems in the past from players who have broken the rules and who have deliberately tried to abuse 1xbit's API. I think it's a really good idea if you post a screenshot of your 1xbit betting summary so we can assess what might be going on. And I'm sure the 1xbit representative will respond as well.
On what sports did you place your bets?
I wish I can show you anything but I can't login to my account so it's impossible for now. I played some casino and some sports betting. My last bets were 4 doubles from UFC, all stakes 200-220 USDT. Some other bets were some u20 basketball etc. Nothing else. I really don't know how could I break anything by doing it? And I was profitable customer for them since I have deposited $5000 and had $3900 or sum when site logged me out. How would you name it but robbery? I just want my money back that I have at my account. Incredible. I am shaking hard from nerves now, don't know what to do, their support can't or don't want to help and security team is ignoring me.
