The Jupiler League is what the Football league in Belgium is called. Sportbet.one is a bookie that runs on the EOS blockchain allowing users to make bets in a decentralized way directly from their own wallet without the need to deposit and trust the bookie site with their funds in an anonymous way with no KYC and such. 3% (which represents the profit they make) of the total volume is being paid out to the ones staking their tokens. I'm making weekly updates on news and dividend payouts buying some more SBET myself last week. (See Post Reasons I Bought More SBET | Weekly Dividend Report)

I hope that answers your questions @crypto.piotr
