What Mercado Bitcoin is
Mercado Bitcoin launched in 2013 and is the largest cryptocurrency exchange in Brazil, with a client base of several million. It offers spot trading focused on the Brazilian real market, along with a range of digital asset products, and has built its presence around Brazilian payment methods and local banking.
The platform is custodial, which means Mercado Bitcoin holds the assets in your account on your behalf rather than handing you the private keys. Users who want to control their own keys move funds to a separate self custody wallet. Its scale within Brazil makes it a reference point for the local market, which is now moving onto a formal regulatory regime.
Where Mercado Bitcoin is available
As of June 2026 Mercado Bitcoin is built around the Brazilian market and serves customers in Brazil who can complete its verification, with deposits and withdrawals in Brazilian real through local rails. It is the dominant domestic platform by user numbers.
Access from the United States and much of Europe is restricted, so the platform is effectively a Brazil focused venue. Anyone outside Brazil should confirm current eligibility directly with Mercado Bitcoin before relying on access.
Regulation and authorisation
- Brazil law. Brazil's Law 14.478, in force since 2023, sets the framework for virtual asset services, and a later decree made the Banco Central do Brasil the competent regulator for the sector (as of June 2026).
- New rules in 2026. The Banco Central published detailed resolutions for virtual asset service providers that took effect on 2 February 2026, covering who may provide services and how providers must be authorised and operate (as of June 2026).
- Transition window. Existing exchanges have a transition period, running into late 2026, to request formal authorisation from the Banco Central and adapt their operations. Authorisation is being granted under the new regime rather than already complete across the sector (as of June 2026).
- Reporting. Mandatory reporting to the Banco Central on virtual asset operations began in May 2026 under the new rules (as of June 2026).
- United States. Mercado Bitcoin does not hold United States registrations and does not serve United States residents (as of June 2026).
Each point is stated as of 13 June 2026. The Brazilian regime is in transition and authorisation status changes. Confirm the current position with the Banco Central and the platform before acting.
Custody, fees, strengths, and limitations
Mercado Bitcoin is custodial. It holds your assets on your behalf rather than handing you the private keys, so users who want to control their own keys move funds to a separate self custody wallet. As Brazil moves onto the Banco Central regime, conduct and reporting requirements are increasing, though that framework does not remove ordinary platform and market risk.
On fees, Mercado Bitcoin applies trading fees using a model that charges different rates to makers and takers, with the exact rate varying by market and order type, plus separate costs for fiat deposits and withdrawals. Pricing changes over time, so confirm the current schedule on the platform before trading.
In plain terms, the strengths are scale and brand recognition within Brazil, deep local currency and banking support, and operation within Brazil's emerging legal framework. The limitations are that it is effectively a Brazil only venue, it does not serve the United States, its authorisation under the new regime is still being completed across the sector, and the model is custodial. None of this is a recommendation to use or avoid the platform, only the factual picture you would weigh against your own country and needs.
Mercado Bitcoin is a Brazil focused venue, and whether it is available to you depends on where you live. Rather than assume, compare the exchanges that are genuinely available in your country before you choose.
Every availability status here is dated and checked against the named regulator's public register. We never place a link to a platform where it is not available.
