When online sports betting was legalized in my state, I was shocked at how aggressive the initial advertising campaign was. There were at least a dozen different sites offering hundreds, if not thousands of dollars of credit with sign up bonus. I distinctly remember sports betting companies offering a variety of "free money" opportunities to onboard new users to their respective platforms. I have never participated in sports betting and have no interest in it, but considering big players in the industry were throwing away buckets of cash in customer acquisition in a way I have never seen before, I can't imagine just how much money they make from their user base once they get hooked.
