It looks like one have a demo account with $ 1000 in play money and can get to know how to bet on the site. good idea
Yep they have a pretty decent and realistic demo account, as i think 1000$ is a recent gambling wallet for what most people would expect to have available so makes for a realistic demo experience of betting to see how your strategies would have worked out.
That said betting on virtual sports, is betting on games like league of legends and esports in general to my knowledge not the same as the demo account i think
So I just need to create my account and 1000$ will be credited to my demo account and i can have betting fun?
you don't have to create an account first. the demo-money can be seen immediately: https://buff88.com/golden-race
you can see it on the top right: DemoUser_GR User credit € 1,000.00
So one can test the site without an account, that's a good idea
