"This string contains 0.25 BTC hiding in plain sight."
Whoever can first figure out how I have hidden the 0.25 BTC gets it. The 0.25 BTC are waiting for you at 1AJ3vE2NNYW2Jzv3fLwyjKF1LYbZ65Ez64 (just sent it now).

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable. I never believe them. If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins. I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion. Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice. Don't keep coins online. Use paper or hardware wallets instead.

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, but full nodes are more resource-heavy, and they must do a lengthy initial syncing process. As a result, lightweight clients with somewhat less security are commonly used.

Do I have to be super geeky to figure this out? |

Found it. LOL. But I mean 0.25 BTC you can actually spend, not the occurrence of the substring "0.25 BTC" in the string. http://blockexplorer.com/address/1AJ3vE2NNYW2Jzv3fLwyjKF1LYbZ65Ez64 |

Given that it is a specific address, it would indicate that the solution will eventually resolve into either a wallet.dat or a private key (and given casascius's service, I'd guess that the solution is a private key) and isn't the login to an online wallet, as those can't guarantee sending from a specific address.
The string is very short and generic, and so it seems a little unlikely that the private key somehow is encoded into it. A private key is 256 bits and the string (assuming casascius is only looking for a-z,A-Z,0-9, period, comma, space, even including the quotes, gives a total of 66 symbols, or ~6 bits per character) has a total of 324 bits... That really doesn't include enough to hide it stego-style in such a pretty sentence.
Given that this is ruled out, its probably more likely to be a logic or lateral puzzle. plain site... site, website... somewhere on his website, view source, ctrl-f, plain.htm, plain.html.
I think I'll give up, never very good at these things.

I bet the SHA-256 of that message is the private key needed to claim the bounty.

Doesn't look like a private key to me... 47510706d76bc74a5d57bdcffc68c9bbbc2d496bef87c91de7f616129ac62b5f Lots of 5's in there though... maybe it starts at a midpoint and goes to whatever characters are necessary for a private key? |

Every 256-bit value is a valid private key. So starting with 5 is just because the PK is generated by the client then? |
