If I was already drawn as a winner are all my other tickets disqualified or are they still in the running for the next prize and then calculations redone if a winner's tickets are drawn again?
Assume that there are 100 users in the lottery and each of them has 10 tickets.
User 1 owns ticket numbers from 1 to 10. User B owns ticket numbers from 11 to 20, and so on. Every week freebitco publish a list in
their twitter to let all users know ticket numbers they own.
Let's say the first ticket picked is ticket number 5. The user A wins the first prize. If the second ticket number is between 1 and 10, that's discarded and calculations are done again.
