What are alternatives most sports betting users are now switching to?
The only alternatives I can think of is online gambling or gaming, sports bettors can choose between the two as long as they are comfortable and they are entertained, because of the lockdown people are fighting boredom and these two online gambling and gaming are the two best option that is very near to sports betting.
eSports betting is one of the emerging alternatives aside from online casinos. I think what you refer as gaming here is eSports as video gamers can compete via online format. And this industry is already multi-million so I believe there are a lot of gamblers who will explore this option.
