Bitcoin Flash Crashed in Brazil to $3,673 usd, on Coinbase, on September 3, 2025. Other cryptos including XRP are reported to have flash crashed as well. It appears to only affect users from Brazil. Maybe the Wealth Transfer is coming to Brazil, first? Many Brazilian users on Twitter reported seeing this flash crash, and buy orders being filled. However, Coinbase sent out an email to the users stating that Coinbase froze their account and plans to recover the incorrectly credit funds (filled orders).

Here is a video one user posted discussing this crypto flash crash. I have included a NoteBookLM summary of the video below:

See my NotebookLM AI Summary below:

The video discusses a bug on the Coinbase exchange where Bitcoin was briefly sold for around R$20,000 to R$24,000 (approx. $3,850 to $4,600 USD), a price not seen since 2016 or 2017. The YouTuber, Leonardo, explains that this was a temporary glitch and not the actual market price.
Key points from the video include:
• The Bug: For a short period, a bug on Coinbase caused Bitcoin’s price to display as low as R$20,562 (approx. $3,950 USD). Other cryptocurrencies were also affected; for instance, Tether (USDT), a stablecoin pegged to the dollar, was being sold for R$0.18 (approx. $0.035 USD).
• A User’s Experience: Leonardo shares the story of an acquaintance who noticed the bug and took advantage of it. This person made two purchases totaling R$38 (approx. $7.30 USD) and received a quantity of Bitcoin that was actually worth around R$913 to R$940 (approx. $175 to $180 USD) at the correct market price. This effectively multiplied their investment by about 25 times. The user chose not to invest more money, suspecting it was a bug and not wanting to risk a larger sum.
• Coinbase’s Reaction: After detecting the bug, Coinbase temporarily froze the accounts of users who had made these purchases. The YouTuber speculates that the exchange will likely cancel the transactions and return the original R$38 (approx. $7.30 USD) to the user.
• Ethical Considerations: The video touches on the ethical dilemma of exploiting such a bug. Leonardo suggests that trying to withdraw the funds might be seen as acting in bad faith, potentially leading Coinbase to take legal action, especially if large sums were involved. He argues that while Coinbase is a massive company, the total losses from the bug could amount to millions, and the exchange would not absorb that loss. He personally believes that if the money isn’t rightfully yours, you shouldn’t take it, and trying to be “slick” in these situations often backfires.
• Historical Context: The video concludes by reminding viewers that to legitimately buy Bitcoin at R$20,000 (approx. $3,850 USD), one would have had to purchase it back in 2017. The opportunity to buy at that price has passed, except for rare occurrences like this platform bug.


Here are various twitter posts I found where people have mentioned this issue (translated from Portuguese):

Some users on Coinbase managed to buy Bitcoin at the rate of 24 thousand reais. Moments after the bug, the exchange froze the accounts of these users and, as far as everything indicates, the orders

It seems like this Coinbase error displaying Bitcoin at R$20k and Ethereum at R$800 is real.
It started popping up with screenshots from my DMs with absurd balances
Would they refund it?

Nobody lost, only Coinbase. I heard of people who took advantage and withdrew more than 800 thousand. These folks will have to prepare the lawyers or return it.

Would you cash out the Bitcoins bought for 20 thousand reais during the Coinbase glitch, or would you wait for the error to be fixed?

Yes, there are reports of a glitch on Coinbase where BTC appeared at ~20k BRL for a short period today (04/09/2025), possibly due to low liquidity or a technical error. The real price is at ~600k BRL. Some accounts were frozen and trades may be reversed. Check official sources.

There is no official confirmation from Coinbase regarding successful withdrawals after the BTC price glitch in BRL. Reports on social media indicate that accounts were frozen and trades reversed, suggesting that most were unable to withdraw. Monitor updates.

Last night (09/03) I had this surprise, when looking at the Coinbase widget on my phone’s home screen, I see the #btc quote at R$20,562.87. At first I got a scare, I didn’t even know what to think, my only reaction was to open the app and place a buy order kkkk

I’m getting some screenshots from some folks who actually did the cleanup on Coinbase, taking advantage of the bug, withdrawing absurd amounts in the millions of reais.
What these people don’t realize is that it’s a nationalized exchange and they could face legal problems if Coinbase decides to go after them.

Hey Léo! Coinbase has already done the automatic recovery of the funds credited to my account, they also removed the restriction. They made 3 automatic BTC sends. It totaled 0.00074645 BTC (456.08 BRL at the current exchange rate).

I believe that those who took a high value might have problems. Imagine the loss for the brokerage! The funniest part is that Coinbase hasn’t even made a statement yet!
