Dear OP, can you provide us with an uncropped screenshot please. There is no way to judge when that screenshot was captured. Our deposit modal has not had that bonus line since the most recent update. It's possible that you were loading a cached version of the page. If you clear your cache and clean your cookies, it should show the updated version.
That's something amazing to hear from a casino. When the OP was trying to deposit the money aka LTC into his account then how possibly a cached bonus could be there? I think something is wrong because with such things any player can get the feeling that they will get bonus when they deposit a certain amount of crypto-currency but in actual they won't get anything and when they make a thread like this then they will get similar reply like OP.
I hope that @OP will get the bonus because he deposited the currency in order to grab the bonus and when bonus isn't there then it means that @OP got scammed somehow. Let's see what steps BC.Game will take in order to solve the issue of the OP.
