Just bought my first batch of tickets. People get in to sweeten the jackpot and it will grow exponentially!!!
One question actually, while I know I have to buy every ticket separately as a 0.25 transaction, is there a problem buying several in rapid succession? So that they might all end up in same block or something and then I only have one hash? Or am I just stupid here?
It's no problem at all. Only the transaction hash is used to determine the winner, and those are unique to each transaction. They are not related to the block they are placed in at all.
