Private key for address with 5 BTC.

[SamReomo]

The most plausible scenario, given this information, is that the OP has no access to the 5 BTC.

I agree with you, I also believe that OP no longer has access to that wallet or has lost it somehow and those who still believe that they can solve the puzzle to earn 5 BTC should read your post at least. I suggest everyone to be careful as there's no chance to get anything from this puzzle anymore.

The private key if found gives access to this BTC addres

Here you can find all addresses that have balances https://bitcointalk.org/index.php?topic=5254914.0
If you find private keys from all of them, you will have a lot of Bitcoins. A rare opportunity with so much free money, isn't it?
