Daily bump.
dooglus's 18e98-1c is the MinAddress to beat.
To answer a question I got by PM: I will probably close out this contest at the end of this month unless there is a lot of activity but I expect activity will die off pretty rapidly as we go farther back into the blockchain.
Any "older timers" want to claim your 0.1 BTC?
I'm unclear about the required 0.1 BTC balance on the address. Does it need to stay on the address, or just be there when you check the address?
I don't really understand why you ask for it to have a non-dust balance at all, since you also require proof of ownership anyway.
Because people (one specifically) cheated by claiming an old address where someone had posted the private key online after using it. They claimed the address as their own and proved it (they did have the private key). However they would not be foolish enough to send BTC to an address where it would probably be swept within seconds. The reason the address must have and maintain 0.1 BTC until I pay them is that someone could go ahead and send a small amount to an old publicly available private key, it gets swept, but they still make a profit on the scam. So, the rule was changed. The winning address must have 0.1 (or more) BTC.
I have also now decided on how to end this thing: X consecutive days with no change in the winning address. I am open to suggestions on what X should be.
