I am sorry for your unlucky, however if you decide to participate in gambling you need to understand the risks that gambling can bring you. Gambling is mostly about luck and you need to accept when luck doesn't belong to you, don't try to blame others for your bad luck.
Until now bitcasino.io is still a very good gambling platform and is used by many people, if you have any evidence that fraudulent bitcasino.io you can put up for everyone to know. . If you have no evidence that bicasino.io and other platforms are fraudulent I think you should retract your allegation.
