For those who had deposited some money on the site, try to reach out the support.
Betbit should be able to provide more information that they will close the site so that the players can withdraw their assets first.
Are you kidding me? why would you expect them to do that when they are planning and exit scam? it's been proven dude, they are gone, so they won't tell anyone, they just get the site offline and take the money, that's it.
The question is "do we know that a site is planning to scam us?" The same also happens in a trusted site named Safedice, there was no signs that they will turn into scam. The site is even still working except for withdrawal. It was one of the oldest and trusted gambling site but something very bad happened eventually. What we can do as players is to be smart as what iv4n said above. Dont put store too much money for a long time any online services including gambling. Once we done with our session, withdraw all our balance. This is to minimize something bad like this issue.
The most important thing to look on a site is whether it's licensed or not, because if a site is licensed, there is likely a lesser chance that they will scam people as they will surely pay for the crimes committed. New or old, license is very important, but if you are willing to take the risk, of course you can play with non licensed site but always be ready of the possibility of scam.
