The relationship between Bitcoin self-custody and the instability of Brazil's traditional financial system, exemplified by the Banco Master scandal, is based on eliminating 'counterparty risk'. While the banking system relies on central institutions and regulators that can fail or be compromised, self-custody transfers total control and responsibility to the individual.
1. Insecurity in the Financial System: The Banco Master Case
Recent events involving Banco Master and regulatory bodies have generated distrust about the integrity of the system:
Payments to Former Executives: Tax records revealed that Banco Master paid R$ 2.2 million to former CVM president, Leonardo Pereira, between 2022 and 2023.
Conflict of Interest: Pereira chaired the CVM until 2017, the body that oversees institutions like Master in capital market operations.
Investigations and Liquidation: In November 2025, the Central Bank declared the extrajudicial liquidation of Banco Master citing liquidity crisis, regulatory violations, and financial compromise.
Alleged Frauds: The Federal Police is investigating a supposed scheme of creating fictitious credit wallets that allegedly caused losses estimated at R$ 12 billion.
2. Bitcoin Self-Custody as a Security Alternative
Unlike the banking system, where the customer's money is a liability of the bank (and depends on guarantees like the FGC, which has limits), self-custody offers:
Individual Sovereignty: By holding your own private keys, you are the sole owner of your assets, without relying on the solvency of third parties or the ethics of regulators.
Immunity to Institutional Corruption: In Bitcoin, the rules are dictated by code (blockchain) and not by humans who may accept improper payments to ease oversight.
Absence of Liquidity Risk: In traditional banks, if the institution fails (like Master), your funds can be frozen. In self-custody, the asset is always available for direct movement by the owner.
3. Synthesis of the Contrast
The fragility exposed in the Master case — where a bank under investigation maintained million-dollar financial relationships with those who should (or should have) overseen the market — reinforces the thesis of self-custody. While in Brazil the investor deals with the risk of regulatory omission and systemic frauds, Bitcoin self-custody proposes replacing 'trust in people' with 'verification in mathematics'.
