The problem is, there are thousands of those lottery participants 50-500 tickets and only one of them wins the lottery, in every 10 rounds maybe. On the other hand, those guys with ~40k tickets win every 3-5 rounds. Sometimes they win every round. So at this point, it is probably pointless to think about winning the lottery unless you are one of those guys with thousands of tickets.
Would be very interesting to see some statistics about money spent on tickets and income based on the winnings. I doubt that those guys with thousands of tickets make any profit.
Are there such statistics available?
