Agree! Everyone can sure do their analysis according to the strength, skill, and weaknesses of the team, players and the opponent, a 100% winning rate in sports bets is a rigged game, We can not predict accurately every detail of the game and how much you can win what if it losses? I guess all you need to do here is to gain popularity and make free service at first so you can sure gain the trust here in the community
