without any research, we don't have a chance to win sportsbetting because in sportsbetting, its all about the update of the each of team and if we can find the info then we only have small chance to win. and before we play gambling, decide how much money we want to spend in gambling and don't ever try to put another money in our pocket when we are loss all of our money, because it will make get quickly empty money.
But we cannot consider sports betting is always the right way of gambling. Because sports betting is also has its own risk levels like match fixing and different playing conditions.
A well performing team/person may not play up to their/his perfection on a particular day due to different conditions. So, the right way of gambling is always doubtful, it may work one day and may not in some of the days.
