The reseacher experimented with eight brainwallets, created by utilizing in style works of fiction, musical lyrics or educational literature, together with all-time classics comparable to Herman Melville’s Moby Dick, and Jane Austen’s Pleasure and Prejudice, but in addition Satoshi Nakamoto’s Bitcoin: A Peer-to-Peer Digital Money System. The experiment’s outcomes have been removed from optimistic for brainwallet customers.

“All of the funds have been swept away inside a day and the 0.04 BTC I spent on this train have been misplaced, probably eternally.

In conclusion, the report suggested crypto house owners to not use a brainwallet generated from revealed supplies. Nevertheless, “by combining many various classes of knowledge, a safe brainwallet could also be potential.”

“In a real-world situation, if somebody (together with a refugee) has entry to Bitcoin, they most likely even have entry to the web and subsequently a safer method of storing cash might be to e-mail your self an encrypted backup of your personal key,” the researcher stated, including that, in the long run, it is also dangerous as the e-mail might be compromised too.
