Just wondering, why doesn't Rollbit support native segwit addresses for Litecoin. This is now a massive platform that should be flexible and always try to stay up to date with the current trends. I tried making a withdrawal sometime back using a native segwit address and got an error of invalid address! @Rollbitcom
Maybe you should try reaching them directly through their online customer care service, I believe you will get a quicker response there than waiting several hours or even days here to get an answer from a rollbit official.
The fact that platform is massive does not necessarily mean they must be updated to every single thing, technology is vast and a lot of things change rapidly that most times, it's choking to try to keep up, some companies have adopted to only updating features based on customer's requests.
What this means is that, stuff or features customers use frequently are always up to date, while those customer don't use frequently lag behind.
Maybe not too many customers use the Litecoin network on the casino, this is reason why it's address system is not yet updated to the latest supported version.
