I wonder why 1xbit gave you back money for your lost bets (voided them) and let you withdraw the full deposit.
After all, if 1xbit wanted to scam you, they could block all your money.

Scam casinos refund player deposits and only steal their winnings because it reduces the chances of the player making a big deal about the fact they were just scammed. Their ideal situation when 1xbit scams a player is that the player just goes away quietly.
When the player loses, 1xbit wins.
When the player wins, 1xbit doesn't lose.
Get it?
Most accurate analogy so in all, it's a win-win for the site, then it's obvious there is nothing like a probably fair system with the bookmaker and that goes a long way to speak volumes about the integrity of the team, I hope one day all this accusation reduce. But in the end, a scam is a scam if the player has evidence to prove the winning before the bet was void by the team.
