How To Bet On March Madness?

While not exactly betting, the most popular option for predicting March Madness results is completing brackets where each fan attempts to attain a perfect bracket. It's never happened, but if and when it does, the winner will earn a hefty payday.
Tips For March Madness Betting
Bankroll management is a priority when declaring your March Madness betting strategy because there are so many games that funds can get depleted quickly. Declare a budget for March Madness betting odds and ensure that it is sourced from disposable incoming - meaning assets remaining after all bills have been paid.
Set a betting limit of 3%-5% of your total bankroll for each game. This will allow at least 20 bets to be made, assuming all of them fail, which is not a likely outcome. It will keep bettors from making hasty wagers and will keep gamblers in the action much deeper into the tournament.
We also suggest belonging to more than one sportsbook because odds are different at each site. If the Duke Blu Devils are favored by 10 at one book and by 12 at another, selecting the line that favors them by 10 will provide an easier path to a win. Being mindful of these three bankroll management strategies will go a long way toward maximizing
