TEDx speaker.

Mike made the decision to dive headfirst into the booming world of sports betting fresh out of college. Back in the day, when 1-800 pick lines and sports pagers were all the rage, he couldn't resist the allure, having grown up idolizing sports legends like Sweetness, MJ, and Slammin Sammy. Mike dedicated his early years to the industry, tirelessly analyzing games, writing articles with free picks, and selling his expertise on reputable handicapping sites. Unlike many others, Mike was known for his integrity and only released one Game of the Year per sport, per season. His hard work and unwavering commitment paid off, earning him a devoted following and propelling his career to new heights. Then came the explosion of Daily Fantasy Sports. Believe it or not, companies like DraftKings and FanDuel used to pay Mike's company to increase their brand exposure. Now, those same industry giants don't even bother responding to his emails. While Mike appreciates the convenience of being able to place legal bets in his own backyard, he can't help but feel disheartened by what has become of the industry. People are being led astray, falsely believing that a mere $5 wager on a 20-team same-game-parlay will be their ticket to financial security. If there’s one thing Mike learned from making book back in the day, it’s that parlays are a bookie’s best friend. A bankroll is the only leg you have to stand on in the battle with the books, and Mike’s here to offer up advice on how to protect it.
