I have read some articles that described repeat lottery wins and claimed that re-purchase of lottery tickets is one of the most profitable strategies if we set ourselves the goal of re-winning.
do you mean betting on past winning numbers? i honestly do not think it will work i have not seen anyone win 2x from the same winning numbers consecutively there is also no pattern here so i do not know what you expect to follow but i guess if you do not want to stress yourself too much trying to think of a set of numbers to bet on then by all means just copy others but i do not know how much it would have given you an edge
