Between revolutionary announcements, technological developments and regulatory turbulence, the crypto ecosystem continues to prove that it is both a territory of limitless innovation and a field of regulatory and economic battles. Here is a summary of the most notable news from the past week around Bitcoin, Ethereum, Binance and Solana, and Ripple.

Brazil envisions its future around Bitcoin
Brazil is preparing for a potential financial revolution with a proposal to create a federal reserve in bitcoin, called RESBit. Led by MP Eros Biondini, this initiative would include up to 5% of national reserves in digital assets, in order to protect the economy against currency fluctuations and geopolitical tensions. Inspired by the example of El Salvador, where bitcoin strengthened the national economy, this project could also support the launch of Real Digital, the digital currency of the Central Bank of Brazil. RESBit would integrate blockchain and artificial intelligence technologies for transparent and secure management, while strengthening local regulations on cryptos. If approved, this proposal would place Brazil among the global pioneers adopting Bitcoin as a strategic tool in their monetary policy.
