Not only this series have any interest nor it has any good betting odds. If you bet on india, you will get so low odds and the profit ratio will be so much low. West Indies odds are high but if you bet on WI, it's very likely that you will lose the bet.
That's the risk you have to take in betting. You would bet on the WI in the next two matches with a limited amount of money. If by any chance, WI won anyone of the match, you can gain good money. I am sure, one match will be won by West Indies but India will win the series.
Indian team is good but not unbeatable. If we look closely at Indian bowling line up then they are very inexperienced in ODI, there are only 2 senior bowlers in current squad Chahal and Kuldeep, latter is warming the bench. At the same time Indian middle order is fairly inexperienced as well.
They are playing against an even more weaker team, West Indies. So even the average bowlers can perform well against them and this will help the younger Indian bowlers to gain more confidence.
