Betting on the same number combinations is difficult for me unless you have the same patience as them to bet for 20 years consecutively. Also, combining all of the money they spend for 20 years, that's a lot of expense nevertheless, it's worth it since they've won $60M. But obviously, this luck won't seem to work with everyone, and this strategy might even take more than 20 years for others. Personally, I'm not a fan of the lottery, and even for other games, I don't stick with the same thing for a long period. But I'm just amazed at their persistence and how they manage to win such a huge amount of prize with it.
