Is their any safe methods to gamble? Means without losing much of our money can gamble?
Any tips or suggestions?
Safe, no.
But you can improve your odds of winning.
Dice games and casino games are all losing bets, no matter what strategy you use, your expected results is always a loss, and the amount of loss is always equal to the house edge. (So if you make 100 Bitcoin worth of bets with a 1% house edge, you can expect to lose 1 Bitcoin).
However, some forms of gambling require skill, such as poker, and predicting the outcome of sports events or predicting other things. If you have a good knowledge of a specific sport and you think you can predict the winner with reasonable accuracy or if you learn how to be a good poker player, you can make consistent money on these forms of gambling, you might still lose a few bets, but the winning bets should cover the losses in these cases.
