Countdown to Brazil's First Bitcoin ExchangeCountdown to Brazil's First Bitcoin Exchange

A Website That Was Only a ClockA Website That Was Only a Clock

On July 13, 2011, a developer named Leandro César posted on Bitcointalk under the title "The countdown to the first brazilian Bitcoin exchange!" and linked to a new domain: mercadobitcoin.com.br. Anyone who clicked through found no order book, no wallet, no price chart. The entire site was a ticking clock, built in Flash, counting down to a launch date. (Being Flash, the countdown itself is now lost — it no longer renders anywhere.) The original announcement thread is still live: https://bitcointalk.org/index.php?topic=28575.0

Forum regular Fireball pointed out the obvious in the replies: the site "only has a countdown on it." César was announcing a product he hadn't finished building. He was writing the exchange in Python and wagering publicly that Brazil would want a Bitcoin exchange by the time the clock hit zero.

One early reply stands out in hindsight. Roger Ver, already one of Bitcoin's loudest evangelists, wrote back: "Bitcoins are going to change the way the world does business. Nice work!"

The Worst Possible TimingThe Worst Possible Timing

The timing looked terrible. A month earlier, Bitcoin had touched roughly $31 — its first speculative peak — and then crashed into single digits. Commentators were writing obituaries for the whole experiment. Launching an exchange into that wreckage took either bad judgment or real conviction.

César moved fast regardless. Within nine days of the announcement, the site had already progressed from a bare countdown to a registration phase: a Google Form with a dropdown asking visitors what interested them about Mercado Bitcoin. The first option in the list was "Vender Bitcoins" — Sell Bitcoins. Early sign-ups were handled through a plain contact address, admin@mercadobitcoin.com.br. This was an exchange being assembled in public, piece by improvised piece.

Why Brazil Was the Right BetWhy Brazil Was the Right Bet

It turned out Brazil was exactly the right market. It was the largest economy in South America and the ninth largest in the world in 2011, yet the Brazilian real was barely served by the international Bitcoin exchanges of the day. A Brazilian who wanted bitcoin faced wire transfers, currency conversion, and platforms that had never heard of their bank.

Mercado Bitcoin solved this the direct way: it took BRL deposits through Banco do Brasil. And it added a second rail that perfectly dates the era — Liberty Reserve.

The Rails of 2011The Rails of 2011

In 2011, Liberty Reserve was just another way to move money online, a digital-currency service used across the early internet-payments world. In 2013, the US government shut it down, and its founder was later convicted for his role in a scheme that laundered $6 billion. That an early Bitcoin exchange plugged into it says less about the exchange than about the landscape: early operators built on whatever payment rails existed, because almost none did.

The One That SurvivedThe One That Survived

Of the exchanges born in 2011, almost none made it. Tradehill closed within a year. Bitcoinica was hacked three times and folded. MtGox, the giant of the era, collapsed in 2014. Mercado Bitcoin — the one that started life as a countdown clock and a Google Form — became Latin America's dominant Bitcoin exchange, and fifteen years on, it is still trading.
