Bitcoin ETFs in Brazil: how they work and when they fit

Buying a bitcoin ETF in Brazil looks like the simplest way to get exposure to the coin: one ticker at your broker, no wallet and no private key. The simplicity has a price and has limits, and most of them only show up when the investor compares the ETF with the alternative of buying bitcoin and keeping it in their own wallet. This guide walks through both routes, from the fund to the tax.

How a bitcoin ETF works on the B3 exchange

An ETF is an index fund whose shares trade on the stock exchange. The investor buys a share the way they would buy a stock, and the fund tracks a reference index. For bitcoin, the index is the coin's price as calculated by a provider, and the fund holds bitcoin, or shares of another fund that holds bitcoin, in enough quantity to replicate that price. The manager decides how to replicate, the administrator runs the fund and a custodian holds the assets.

The best known funds come from Hashdex and QR Asset. BITH11, the Hashdex Nasdaq Bitcoin Reference Price FI, tracks bitcoin alone, charges a maximum total fee of 0.7% a year, has Banco Genial as administrator and custodian, and held R$ 1.50 billion in assets on September 24, 2026, according to the fund page. HASH11, tracks the Nasdaq Crypto Index, a basket in which bitcoin weighed 73.4% on the same date, charges a 0.3% annual management fee with total costs capped at 1.3% a year, and held R$ 2.88 billion. QBTC11, from QR Asset, tracks the CME CF Bitcoin Reference Rate and has Vórtx as administrator.

Some of these funds do not hold bitcoin directly: ETHE11, from the same manager, invests at least 95% of its assets in a Cayman Islands fund, so the Brazilian investor holds a share of a fund that holds a share of a fund that holds the coin. That is not a problem in itself, but it puts layers of counterparties between the investor and the asset, and each layer has its own fee, regulator and trading hours.

What changes versus holding bitcoin yourself

The central difference is custody. With the ETF, the share is registered in your name at B3 through your broker, and the bitcoin sits with the fund's custodian. You have no key, cannot move the coin to a wallet and can only trade during exchange hours, while bitcoin trades 24 hours a day, seven days a week.

With bitcoin in your own wallet, you hold the asset rather than a claim on it. In exchange, you take responsibility for the key, the backup and the succession plan. A hardware wallet costs a fixed amount, paid once, and charges no annual percentage; an ETF at 0.7% a year on R$ 100,000 costs R$ 700 every year. The custody models and the most common mistakes are covered in crypto custody: self-custody vs third-party custody.

Succession differs too. An ETF share goes into probate like any listed asset, and the broker knows it exists. Self-custodied bitcoin is only inherited if someone knows where the key is and how to use it.

Tax: ETF on the exchange versus direct crypto

In Brazil, the ETF follows the rules for stock exchange operations. Under question 676 of Receita Federal's IRPF Questions and Answers, the net gain is taxed at 15%, or 20% for day trades, and the broker withholds 0.005% at source as an advance. Question 677 is explicit: the R$ 20,000 monthly exemption for stocks does not apply to index fund shares. Every gain on an ETF is taxed, whatever the amount, and the tax is paid monthly.

Bitcoin bought directly follows the capital gains rules for crypto assets, question 627 of the same document. If total sales in the month stay within R$ 35,000, the gain is exempt; above that, progressive rates starting at 15% apply, with payment due by the last business day of the following month. The ETF has no such exemption.

On the annual return, the ETF share is declared as a fund holding, and the broker sends the statement. Self-custodied bitcoin goes in group 08 of the assets schedule, and anyone operating outside a Brazilian exchange above R$ 35,000 in a month has filed the DeCripto report since July 2026. The ETF generates no DeCripto.

When the ETF makes sense, and when self-custody does

Picture an investor who wants 3% of their wealth in bitcoin, already has a brokerage account, does not intend to use the coin and wants the family to find the asset in probate. For them, the ETF delivers price exposure with the least new operational work, and the annual fee is the cost of that convenience.

Consider instead someone who plans to hold bitcoin for ten years, in a meaningful amount, and wants the asset outside any counterparty. Every year the ETF fee takes a slice of what they own. For that profile, buying the coin, learning to store it and documenting succession is usually worth the effort, and the R$ 35,000 monthly exemption helps when the time comes to sell gradually.

Between the two extremes, many investors combine both: an ETF for the part that needs to be simple and self-custody for the part that needs to be theirs. The crypto-asset market involves high risks, including significant volatility and the possibility of losing the invested capital. This article is educational and does not recommend buying any fund or asset.

Frequently asked questions

What is the largest bitcoin ETF on B3?

Among Hashdex funds, HASH11 held R$ 2.88 billion in assets on September 24, 2026, but it tracks a basket of crypto assets. BITH11, which tracks bitcoin alone, held R$ 1.50 billion on the same date.

Does a bitcoin ETF get the R$ 20,000 or the R$ 35,000 exemption?

Neither: the R$ 20,000 exemption applies to stocks, and Receita Federal states it does not apply to index fund shares, while the R$ 35,000 exemption applies to direct sales of crypto assets. Every ETF gain is taxed at 15%, or 20% for day trades.

Can I withdraw the ETF's bitcoin to my own wallet?

No. The share is a claim on the fund, and redemption, where available, is in cash. Anyone who wants the coin in a wallet must buy bitcoin on an exchange and transfer it.

Does a bitcoin ETF pay dividends?

No. Bitcoin generates no income, and the fund only tracks the price. What the holder gets is the change in the share price, minus the fund's fee.

Let's talk

If the question is how much of your wealth to put in bitcoin and whether that slice belongs in an ETF, in self-custody or in both, the answer depends on horizon, amount and who else needs access to the asset. Vault Capital is a securities advisory firm authorized by the CVM under CVM Resolution 19/2021 and never takes custody of client assets. The first conversation puts that choice into numbers.
