This is not growing a lot because they just updating what's already in there as their old feature. Growing means their traffic and volume increase since this makes casino bigger. The addition of house game can considered too as good growth but it's not that big improvement since all this update is useless if their traffic and native token is not moving forward.
You can use the utility token growth as measurement for casino improvement since investors will keep buying this token if there's something big upgrade happened on the casino which is not all. I agree on o48o suggestion.
Maybe improving is a better word than. It would be interesting if the team wants to share their traffic and volume increases after the changes, I can only imagine it should be higher than before even with the long list of restricted countries. I know we keep talking about the price of the BFG tokens, but lets give them a bit more time also.
