Hello, we just opened up and have already seen a lot of scammers on the site, so algorithms were introduced to identify such people.
You can write to the e-mail support@truflip.io and we will help to solve your problem. Now Withdrawal works;)

As for the rest of your questions, in the near future we are planning an announcement and opening of an official topic in the Bitcoinstall forum, where we will answer all questions, including yours.
