I notice this post and have joined yesterday. You need metamask to participate. When I have joined they gave me 5000 of tokens to start placing bets. I got some points from betting on the platform. Good thing is you can bet until world cup is in place. You can win tokens just by placing your bets and wining the bets, if your team/prediction was accurate, you get more points back. It is like real betting but just on blockchain.
They are giving the opportunity how to openly and transparently use ethereum blockchain for betting and to make other form of validation in more transparent way. I see potential of this not just for betting but, elections, law making, contracts, money transfers and donations to charity like UNICEF. So people can know where the money really go.
