In regards to your recent change of rules for Bitlotto.

1) You are absolutely correct in your latest change.  Your new scheme is much more secure.  I don't see any statistical problems with it.

2) It is absolutely possible to select transaction IDs.  You simply use a client like bitcoinJ which allows you to create a bunch of transactions then examine/simulate with them to see which one helps you cover the most lucky number space in conjunction with your other transactions.  Then you commit only those transactions that help you the most.

With that, I was able to get a 2 to 1 expected return for this months draw.  Controlling about 15% of the ticket value I had about 30% win chance.  Well, until your rule change.

I was planning on speaking up this draw but oh well.  I could claim my plan was a valid strategy and within the rules however I was clearly attempting to violate the spirit of a random lottery so I can't honestly complain.

Now my odds are the same as all the other dumb money chumps.

Close call then.

WOW! I wasn't expecting someone actually already doing it. I'm glad I did change it then. Sorry I prevented you from gaming the system! I try to do everything in my power to make it fair. Thank you for being a good sport about having your strategy wrecked. I had to do it of course.

I'm curious how long did it take to create something to do such analysis?

Interesting that he ended up winning anyway.  So much for the concept of karma.
