A 50 reais note containing the equivalent of another R$400 in Bitcoin has been circulating throughout Brazil since December 2022. As the amount has not yet been redeemed after 10 months, we can say that no one who took the note discovered the secret.
The R$50 note contains 12 words in English that give access to around 0.003 BTC. To redeem the amount, simply download a wallet, enter the words and transfer the bitcoins to a new address.
If the balance is not redeemed by the next Bitcoin halving, the creators say they will donate the amount to a charity.
