Yeah random.org should have been used 
How would random.org be used? The op could say "Yes I used random.org and the number was 213" (which could be a sockpuppet's number). Is there a way to verify that random.org was used?
BTW, the strategy used by the OP is not random at all (the output is not uniformly distributed). In fact it should be easy to prove that there are certain numbers that *could never have been generated*.
Does it matter? It's his BTC to give away. Read the haiku above.
Its his BTC and if he really gave it away its pretty cool. But without a proof, its not simply credible enough.
Provable security is pretty cool. What the OP should have done is
Give the strategy for the random number before data collection is complete. So other users have opportunity to add randomness.
That aside, what's more interesting are the comments to use random.org
I'd really like to know how it'd work.
Come on, the rules were on, everyone knew them and the contest has a winner.
You can't ask for more, transparent or not.
Would you be happier if instead of having a contest, using random.org or other method, he just gave the btc to someone he knew without even promoting the opportunity for the rest of us?!
And I also question all those who still post addresses like mad here: have you already read the post?! What part of ended didn't you all understood?!
Come on! You should be thankful, not questioning! That's a complete nonsense!
Thanks
