Our Foxbit review for PAXG buyers in Brazil

Verdict and score

Foxbit is a Brazilian crypto exchange that offers a direct PAXG/BRL market. For a resident who keeps money in a Brazilian bank, that is the main appeal. You send reais by Pix, place an order, and end up holding PAX Gold, the token issued by Paxos Trust Company, N.A. that represents one fine troy ounce of a London Good Delivery bar per token. There is no detour through USDT and no foreign-exchange step at a card issuer.

We scored Foxbit 7.1 out of 10 for buying and holding PAXG. It earns high marks for Pix funding and for publishing a clear fee table. It loses points because we could not find any trading-volume data for its PAXG book, and because Brazil’s new authorisation regime for crypto firms is still in its transition period. If you are new to the token itself, start with what PAX Gold is before you open any account.

Foxbit at a glance

The table below sums up what we could confirm on 12 October 2026. Where a fact comes only from commonly reported company information, we say so. Foxbit’s founding year is often given as 2014, but we did not find it on an official page during this check, so treat it as unconfirmed.

The PAXG/BRL market on Foxbit

Foxbit’s own public markets API returned a PAXG/BRL market on 12 October 2026. That is the strongest evidence we have that the pair exists and is set up for trading. The same data did not show a PAXG/USDT or PAXG/BTC pair, so on Foxbit you buy gold tokens with reais only.

Liquidity is the open question. CoinGecko’s ticker list missed Foxbit’s PAXG market entirely, which means we have no aggregator snapshot of its daily volume. For context, the other Brazilian PAXG/BRL book, at Mercado Bitcoin, showed only about US$4,000 of volume over 24 hours on aggregator data from the same day. That is tiny next to the global PAXG/USDT books on large venues. In practice, expect a wider gap between the best bid and ask than you would see on a global market.

Why does that matter for gold? PAXG’s fair value tracks spot gold, because Paxos creates and redeems tokens against real metal. On a thin local book, the BRL price can drift a little above or below that fair value, especially when the gold market is closed at the weekend. Before you buy, convert the live gold price into reais with our gold calculator and compare it with Foxbit’s order book. Our PAXG price page explains premiums and discounts in more detail.

Trading fees

Foxbit publishes a tiered fee table based on the reais you traded in the last 30 days. The tier is recalculated every day at midnight. We read the page on 12 October 2026; the table showed no effective date, and the page says changes are announced in advance through official channels, citing BCB Resolution 520/2025.

Most PAXG buyers will sit in the entry tier. Here is a worked example. If you buy R$5,000 of PAXG with a market (taker) order, the fee is 0.50%, or R$25. If you place a limit order that rests on the book and fills as a maker, the fee is 0.25%, or R$12.50. Selling later costs the same again. A round trip as a taker is therefore about 1% before any spread, which is fine for a long-term gold holding and expensive for frequent trading.

Remember that the exchange fee is only part of the cost. Paxos itself charges no on-chain transfer fee on PAXG today, and its creation fees are waived until 1 January 2027, but those Paxos fees apply to Paxos accounts, not to your trades on Foxbit. Our guide to PAXG redemption and fees breaks down what Paxos charges and when.

Pix, TED and withdrawals

Pix is where Foxbit is strongest. Its fee page says Pix deposits are processed every day, including holidays. TED, DOC and cash deposits are approved Monday to Friday between 8:00 and 16:30, and anything sent outside those hours is credited on the next business day. The page did not print a fee amount for either deposit method, so look at the deposit screen before you send money.

Withdrawing reais to your own bank account is listed as “Taxa zero”, which means free. That is a real advantage if you plan to sell PAXG later and move the money back. Crypto withdrawal fees are a different story. The fee table did not load during our check, and Foxbit says the amount depends on the blockchain network and may change without notice. Check the current figure on the withdrawal screen before you move PAXG out.

If you do withdraw, the token you receive must be the genuine one. On Ethereum, the official PAXG contract is 0x45804880De22913dAFE09f4980848ECE6EcbAf78. Paxos made Solana an official network on 25 June 2026, but it has not published the Solana mint address in a way we could confirm, so verify any Solana address on paxos.com. Our PAXG networks guide and wallet guide cover the details.

Regulation and safety

Brazil’s crypto law, Law 14.478/2022 (the Marco Legal dos Criptoativos), puts virtual-asset service providers under the Banco Central do Brasil. BCB Resolutions 519, 520 and 521 were published on 10 November 2025 and took effect on 2 February 2026. Resolution 520 created a new class of licensed firms, known as SPSAVs, in three types: intermediary, custodian and broker.

Firms that were already operating, like Foxbit, have 270 days from 2 February 2026 to apply for authorisation. By our count that deadline falls in late October 2026. Resolution 548 then gives the central bank up to three years to decide on those applications. So, as of 12 October 2026, Foxbit operates under the transition rules. We found no public BCB list of granted SPSAV authorisations, and we will not claim a licence we cannot confirm.

On security, we did not find verified reports of a major incident in the research we used for this review, but we also have no independent audit or proof-of-reserves data to cite. That is why the security score sits in the middle. The fact that the fee page already refers to BCB Resolution 520 is a small positive sign that the company is working inside the new framework.

There is a second layer of risk that has nothing to do with Foxbit. Paxos can freeze tokens and upgrade the PAXG contract, and the gold sits in LBMA vaults in London. Read is PAX Gold safe and how the gold backing works for that side of the picture.

Tax for Brazilian residents

This is a general summary, not tax advice. The proposed Provisional Measure 1.303/2025, which would have set a flat 17.5% rate, lapsed without becoming law. That leaves the earlier regime in place. Individuals selling crypto on a domestic exchange are exempt for sales up to R$35,000 per month. Above that, gains are taxed progressively from 15% to 22.5%.

The contrast with foreign platforms matters. Crypto held on foreign exchanges is taxed under Law 14.754/2023 at 15% a year, with no monthly exemption. That is one reason a domestic venue like Foxbit can make sense for a modest PAXG position. Our PAX Gold in Brazil guide covers tax, Pix and local options in more depth, and the Receita Federal is the authority to check.

How to buy PAXG on Foxbit

1. Open and verify an account

   Sign up on the official Foxbit site and complete identity checks with your CPF. Use the link in our hero rather than an ad, to avoid fake sites.

2. Deposit reais by Pix

   Pix deposits are credited every day. TED and DOC are approved only on business days between 8:00 and 16:30.

3. Check the fair price

   Convert the gold price into reais with the gold calculator and compare it with the PAXG/BRL order book.

4. Place a limit order

   Set your price on PAXG/BRL. A resting limit order is usually charged the 0.25% maker fee instead of the 0.50% taker fee.

5. Decide on custody

   Keep small amounts on the exchange, or withdraw to a wallet after checking the network and the current withdrawal fee. See our how to buy PAXG guide for wallet steps.

Pros and cons

Alternatives in Brazil and abroad

If Foxbit’s book looks too thin on the day you want to buy, compare it with the options below. Mercado Bitcoin is the other domestic PAXG/BRL venue. Global exchanges offer far deeper PAXG/USDT markets, but no BRL pair and no Pix, and the foreign-exchange tax rule applies. CEX.IO, in business since 2013 and licensed as a money transmitter in 38 US states plus DC, accepts users from Brazil and lists PAXG against USDT, USD, EUR and USDC, with card payments rather than Pix.
