In my opinion, betting alone is a problem. 
However, if you choose between regular bets and blockchain bets, I will always choose blockchain. Because blockchain involves the absence of any manipulation.
Sports betting, like casinos, has a large monetary share in the world market, which means that a large number of people are somehow involved in these types of activities, which will have a very positive effect on mass adaptation if casinos and blockchain rates are more widespread.
