This is a common experience for many people who are just starting something new because they don't have enough knowledge or experience yet. With more interaction and time, beginners will get used to it and feel more comfortable. This is a natural process of learning. Everyone must have been in this position, feeling confused and cautious when first entering a new system. However, with persistence and time, these obstacles will disappear.
Fact is sportbet.one is not new platform at all. They started in 2019 and till this date it's been around 5 years :-D
They used to have a signature campaign on this forum long time ago.
Recently they are also making some plans for marketing to push the brand in front of the bitcointalk members.
