Look I don't know about this wallet or exchange, but I must give you guidelines.
If you have your money in exchange then fine you can rest your password, maybe within 24-48hrs you would have access back. But if your funds is in a wallet that has seed phrase then it's better not to stress anyone here because only the seed phrase key would be used to access the wallet. However, I can't see this rewards to be something very bad rather it looks like trying to fish people into your game. Those who doesn't have such amount would quickly jump to accept such offer to help you out but I believe at the ends it would be a reversed case, so, anyone helping should be extremely cautious as scammer could used any way to lure people into their scamming scheme.
