No, the account key is only accessible through your IP, the chances of the account getting "hacked" are about as big as someone bruteforcing your private key.
This is not what I asked. I asked what you would do if the CasinoBit website itself was compromised.
However, this raises an even bigger issue. Based on this explanation, if an investor has a dynamic IP address or switches ISP's they lose their investment? You might want to rethink this system and just use accounts with passwords and 2FA like Just-dice.com. I wouldn't want access to my investment/balances to be dictated by my ISP
You can always contact the support in this case, point is that the account is always accessible from just 1 IP and it is likely to remain so.
If the website is compromised (which is highly unlikely since we follow the highest standards of security) then you lose your investment, it obviously DOES have risks like any other investments out there so people need to be adults about this.
