But there is a slight Caveat to these Bets which is the fact that there are some random mischievous players who Bet on these Games provided they are able to get into the same Lobbies as the Bet Lobby and they start to throw the game away so that they can win some Big Money on the BET they made.
So they bet against themselves, and they let the enemy team win to win big money? Doing this is ranked games is indeed ruining the game. This is a type of cheating. Riot Games probably will ban them. Either temporarily or permanently.
