Why Did Coinext Close? Brazil's 2026 Crypto Exchange Shutdown

Coinext served more than 420,000 customers during its years in Brazil's cryptocurrency market. By October 2026, the exchange was closing the trading business that brought those customers in. The company said new regulatory capital requirements had made continuing uneconomic.

Trading ended on 15 October 2026. But Coinext did not say every account had to disappear that night. Instead, it separated the end of crypto trading from the return of customer money in Brazilian reais.

That distinction is central to the closure. Someone with an old Coinext balance faces a different question from someone seeking an active exchange: what assets were converted, what remains withdrawable and how can they obtain their records?

A Brazilian exchange with a sizeable customer history

Coinext began operating in 2017. In its September farewell message, the company said it had accumulated over R$14 billion in historical trading volume and served more than 420,000 people.

These are operator-reported lifetime figures, not audited balances at closure. They do not tell us how many customers still held assets in October or the amount requiring repayment.

InfoMoney reported on 4 September 2026 that Coinext was the fourth Brazilian crypto platform to announce an exit since April. The report also distinguished the closing retail exchange from the group's Coinext Asset operation, which it said remained active for institutional clients.

An operating company can discontinue one regulated service without dissolving every entity in its group. Coinext says its corporate structure will remain available to process outstanding BRL withdrawals.

Why Coinext chose not to seek authorisation

Coinext directly linked its decision to Brazil's new rules for virtual-asset service providers. The company's closure FAQ says it did not meet the required minimum regulatory capital for an authorisation application to the Central Bank.

Management said it assessed possible partners and alternatives. It concluded that none offered a viable path to continue the brokerage. Those are the operator's stated reasons, not a finding that it was ordered into bankruptcy.

The underlying rules are documented in the Central Bank's Resolution BCB 519, which governs authorisation procedures, and Resolution BCB 520, which addresses the operation of virtual-asset service providers.

The capital requirement depends on the regulatory framework and the services involved. Coinext's explanation should not be turned into an unsupported claim that every Brazilian crypto exchange faced one identical amount. Nor does failing a capital requirement establish that customer assets had been stolen.

The timing also connects Coinext to NovaDAX's withdrawal-led closure and Digitra.com's abandoned licensing plan. Each operator, however, set its own timetable and arrangements for former customers.

The withdrawal timetable changed after the first notice

An older Coinext FAQ, reproduced on Reclame Aqui, set a crypto-withdrawal deadline of 20 October and automatic conversion beginning 26 October. Those dates were superseded.

The updated official Coinext FAQ instead sets the final request deadline at 16 October 2026, 23:59 Brasília time. It brought forward the start of automatic liquidation to 17 October, 00:00. The trading deadline did not change.

Times are Brasília local time. The operator's updated schedule is the controlling source for this table. It distinguishes a scheduled process from independent proof that every transfer or sale succeeded.

This is why relying on a first shutdown announcement can be dangerous. Customers reviewing historic notices need to compare them with the latest operator guidance, especially when a deadline is shortened rather than extended.

What happened to cryptocurrency left in an account?

Coinext amended its terms in August to allow the conversion of assets that customers did not withdraw before the deadline. It said remaining eligible crypto would be sold at market prices and credited as Brazilian reais.

The FAQ explains that liquidation may occur in batches. A thinly traded asset might achieve a different price from one quoted on another platform. The company does not guarantee a particular conversion price or outcome.

Not every token was necessarily convertible. Where liquidity was inadequate, the operator said the asset could remain on record for a specially arranged external transfer. An account with a pending withdrawal or unresolved support case could also be treated differently.

The operator said withdrawal requests placed by the October 16 cutoff would continue to be handled even if blockchain confirmation came later. That distinction matters: requesting a transfer and receiving the coins are separate steps.

Japan's LINE BITMAX shutdown also involved converting crypto left behind into local currency. Its legal arrangements and customer deadlines were different, so its outcome cannot be assumed for a Coinext balance.

Coinext says BRL withdrawals have no final deadline

A customer who missed the crypto cutoff has not necessarily lost their money. Coinext says converted balances will remain available in Brazilian reais for an indefinite period, provided the account is eligible for withdrawal.

The company directs customers to withdraw through Pix to an account under the same CPF or CNPJ. Its FAQ specifies that this is the supported BRL withdrawal channel. Identity verification and account restrictions may still affect the process.

Coinext says standard BRL transfers can take up to two business days, although they often happen sooner. The firm expects manual requests after the ordinary platform window to take longer.

The company also says balances remain segregated and available. That is an assurance made by Coinext, not an independent audit proving that every individual claim has been settled.

This is a different situation from Knaken's court-ordered bankruptcy, where the recovery of missing customer assets had to be examined by a trustee. It would be inaccurate to treat Coinext's planned refund process as evidence of a similar shortfall.

What if an asset was locked in staking?

Some Coinext users held assets through staking arrangements. Unlike a liquid token in a trading wallet, a staked asset might be subject to a blockchain protocol's own unlocking timetable.

The operator's closure instructions say it initiated unstaking processes and would make assets available as protocols released them. Where unlocking extended beyond the standard exit window, Coinext said affected customers would receive individual instructions.

A pending unstaking request should not be confused with missing funds. It also cannot be counted as a successful repayment before the asset is available and transferred or converted.

Why Coinext recommended other exchanges without transferring accounts

Coinext named Mercado Bitcoin and OKX as possible places where users could open accounts after the closure. It presented them as optional destinations, not as automatic successors holding everyone's balances.

Customers could also transfer eligible crypto to a wallet they controlled before the deadline. The exchange's FAQ says its recommendations were not paid referrals and that Coinext did not guarantee those providers' services.

A recommended exchange and an asset migration are not the same thing. In DMM Bitcoin's wind-down, a separate arrangement transferred customer accounts and assets to another operator. Coinext's notices instead described customer-directed withdrawals and optional alternatives.

Account histories have a later deadline

Even after trading closed, account records remained important. A customer may need old trading histories to reconcile deposits, verify a past conversion or prepare Brazilian tax documents.

According to the company's schedule, self-service access to statements and transaction histories remains available until 30 November 2026. From December, customers can request documents through a manual support channel.

That is a future records-access deadline as of 25 October 2026. The company says reports will remain preserved under applicable legal retention requirements, but direct online access will change.

Customers should retain trade confirmations, bank statements and blockchain transaction identifiers. They should also verify any unusual request through the original operator's channels. Coinext warns that scammers may impersonate support staff or offer faster withdrawals in exchange for private keys or payments.

Was Coinext the same exchange as CoinEx?

No. Coinext is the Brazilian cryptocurrency exchange discussed in this article. CoinEx is a separately named international exchange. Their closure notices, corporate entities and customers must not be confused.

The spelling is close enough to cause mistakes in search results, particularly when both names appear in discussions of exchanges stopping services. The facts here concern Coinext's Brazilian brokerage and its published 2026 wind-down.

What the Coinext case tells us about exchange closures

Coinext's retail trading stopped in October, but its obligation to return remaining customer money did not end with the trading book. Its corporate presence and BRL support were expected to continue.

Other closed cryptocurrency exchanges followed very different paths. Some entered liquidation, while others kept withdrawal-only services open. For former customers, the last trading day and the last possible recovery date should never be treated as interchangeable.

Coinext's record should therefore reflect a completed October 15 trading shutdown and an ongoing BRL withdrawal process. An eventual company dissolution or verified final return of all assets would require separate evidence.

Sources and verification

The main primary source is Coinext's current closure FAQ, including updated deadlines and customer-asset arrangements. Its farewell statement reproduced on Reclame Aqui gives the operator-reported historical customer and trading figures.

The older timetable on Reclame Aqui is retained as evidence of earlier deadlines, not as current guidance. InfoMoney's September report supplies independent business context. The Central Bank's Resolution 519 and Resolution 520 establish the regulatory framework.

Information checked 25 October 2026. Operator claims about segregation and customer balances are attributed. No bankruptcy, verified customer deficit or universal payout percentage is asserted.
