Umm... I think what mitchr4 refers as "new" here is from the player side, not the [age of the] site itself, as in the learning curve every people experienced when they're interacting with a platform for the first time.
If you have gambled before then you know what to expect whenever you log in to a similar casino with a different name even if it is a new platform. Almost all casinos offer the same basic features, it is just the arrangements on the platform that is different, and maybe a different name for it.
Only complete noobs without any idea or experience with gambling in an online platform will find it difficult, and slower to understand the platform.
The SportBet.one platform is very user friendly to me, and easy to Navigate.
