Actually, let's make it a challenge.

This is a 120 bit private key with the remaining part all zeros: 5HpHagT65TZzG1PH3CSu63k8EXXXXXXXXXXXXXXXXXXXXXCggk4

This number of bits have been solved in the infamous puzzle challenge, but with great computational effort.

The address is 1HCQXqpBwLpwWQ2F2995PwcAPVkTdtpAHe - I've now used it in four transactions so that gives you four signatures. Feel free to claim it. I will in addition give you 0.03 BTC if you give a full explanation with code after claiming it.
Don't you think paying pennies for gold is a bit of insult? If you want the challenge accepted, make it 100 btc.

It's not really "gold" since it's such a special situation, where over half of the bits of the private key is known. Just curious if someone manages to find a way where multiple transactions (with proper nonces) actually weakens the security of such a key.
