Brazil's House of Representatives is reviewing a bill to establish a sovereign Bitcoin reserve, potentially allocating up to 5% of the country's international reserves to Bitcoin investments. The initiative, outlined in Bill No. 4501 of 2024, aims to diversify Brazil's treasury assets, mitigate exchange rate and geopolitical risks, and support the development of blockchain technology and the Brazilian digital currency, Drex. The proposed Bitcoin reserve, known as RESBit, would be managed by the Central Bank of Brazil and the Ministry of Finance. It would employ security measures such as cold wallets and a strict transparency mechanism. Rapporteur Luiz Gastão supports the bill, advocating for a cautious and gradual implementation to balance the benefits and risks associated with the investment.
