Many tickets do not necessarily have many chances because basically games like this only rely on luck without any skills as long as you have enough money, buying a few lottery tickets is more than enough, I once heard a story about my friend winning the lottery and he only had a few tickets there, proving that lots of tickets not much chance of winning either.
It depends to a perspective and status of a person, if they have a means to buy a lot of lottery ticket then it will not be an issue and as a matter of fact, many people are doing that in our country especially those who really loves buying lotto tickets, as in everyday they bought tickets and betting in the same numbers. But for me, even that I have the means to buy many tickets, I choose not to, because it's not practical for me and I believe that if luck is really for me, even if I only bet on one ticket, I will win. I don't need to spend a lot and expect to win.
That's the reason why its not necessary to buy a lot of tickets since if luck is not on our side for sure those bought tickets will just be useless since we can be defeated by those people which only acquire single or few tickets.
So its not good to waste our money for doing that since the chances still the same.
Also if we came to the point where we came on that situation which we think that buying a lot of tickets will be more beneficial to us and we spend a lot of money just for that I think we need to check ourselves since we might didn't notice that we are slowly falling into addiction state.
