Beware all ye who wonder down these paths where brainwallet.org and other brainwallets may lie. Many a person has stated warning from afar, such as tech wizard Jeff Garzik who shouted “No!” firm warning raised, and such as Robin Hood (of the Digital Age), where our tale lies today.

The term ‘brainwallet’ has been in the Bitcoin space for a while; the first I heard about it was last summer (2013). Being a cautious person myself, and not a coder, I waited patiently whilst others experimented with this new thing, brainwallet.org.

Brainwallets are Bitcoin wallets generated uniquely from a passphrase that the users keeps in his mind so that it is required and sufficient to move the funds.

Soon I heard about people losing their funds via the site, and reading through a variety ofwarnings on bitcointalk I decided never to use the site myself.

The consensus is that humans simply cannot generate a secure brain wallet versus someone with an FPGA farm (a relatively fair amount of computing power).

FOR GOD’S SAKE. DON’T DO IT. YOU MAY THINK YOU ARE SMART ENOUGH. SO DID EVERYONE ELSE WHO GOT ROBBED. HUMANS ARE NOT A GOOD SOURCE OF ENTROPY.

~Jeff Garzik

Unfortunately amongst the list of warnings not to use the site there is the sporadic message from some poor unfortunate who did indeed use the site, and promptly lost all their bitcoins they deposited.

However, for the unlucky and too trusting out there, or those that were simply fooled by a scam site or similar, there is Robin Hood (btcrobinhood), who tirelessly roams the digital woods looking for things to right.

His most recent service to the community has been to swipe and return 35 bitcoins from someone who had mistakenly decided to use brainwallet.org. As has happened recently with this particular redditor,he deposited 35 Bitcoins, which quickly disappeared.

I had 35 Bitcoin spread across 18 wallets and the coins have been sitting idle for months. Sometime last night, all 35 coins were moved to two addresses

A tragic blow, that lost him “95 of his Bitcoin Holdings”. He was fortunate in this case as Robin Hood was soon on the scene.

Robin Hood in this scenario is something that is referred to as aWhite Hat hacker, someone who hacks with an altruistic nature (someone who gives and cares for others rather than takes and cares just for themselves).

Robin Hood returned the 35 Bitcoins ($20,440 on 27th June ($584) average).

So as a warning to one and all;
