Born in the ashes of the global financial crisis of 2008, Bitcoin has established itself as a radical response to the flaws of the traditional financial system. More than just a digital currency, it embodies a movement, a philosophy, and today, a globally recognized asset. This article immerses you in the fascinating world of Bitcoin, from its mysterious birth to its growing adoption around the world.

In October 2008, a certain Satoshi Nakamoto, a mysterious character whose true identity is still unknown, published a white paper entitled "Bitcoin: A Peer-to-Peer Electronic Cash System". The idea: to create a decentralized digital currency, without intermediaries, resistant to censorship and manipulation.

On January 3, 2009, the first block of the Bitcoin blockchain, the Genesis Block, was mined. In this block, Nakamoto leaves a coded message:

“The Times 03/Jan/2009 Chancellor on brink of second bailout for banks.”

This message refers to a Times article, illustrating the loss of confidence in central banks and controlled monetary systems.

Bitcoin is based on three fundamental pillars:

A. The Blockchain

A public, immutable and distributed register that records all transactions. Each block of data is linked to the previous one, forming a secure and transparent chain.

B. Mining (Mining)

Miners validate transactions by solving complex cryptographic equations. As a reward, they receive new bitcoins. This process ensures the security of the network.

C. Decentralization

No government, bank or individual controls Bitcoin. It works thanks to a global network of independent nodes, ensuring its robustness against censorship and manipulation.

Economic Foundations of Bitcoin

• Limited quantity: There will never be more than 21 million bitcoins, making it a deflationary asset.

• Predictability: The issuance of bitcoins is halved every four years or so (the halving), which reinforces the scarcity.

• Portability and divisibility: A bitcoin can be divided up to 8 decimal places (satoshis), making its use accessible to all, even with small amounts.

Initially, Bitcoin was worthless. In 2010, a famous transaction made it possible to buy two pizzas for 10,000 BTC. Today, these bitcoins are worth several hundred million dollars!

Here are some milestones:

• 2011: 1 BTC reached parity with 1 USD.

• 2017: Bitcoin exceeds $20,000.

• 2021: It reaches a historical record of more than $69,000.

• Today (2025): It is considered a store of value by many institutional investors.

The adoption of Bitcoin continues to grow, driven by various factors:

In many countries, including Africa, Latin America and Asia, Bitcoin is used to protect savings, send money abroad, or pay without a bank.

Giants like Tesla, MicroStrategy, and Square have bought Bitcoin as a cash reserve.

In 2021, El Salvador became the first country in the world to recognize Bitcoin as legal tender. Other countries are considering the possibility of following this path.

Despite its success, Bitcoin faces challenges:

• Energy consumption related to mining.

• Increasingly strict state regulations.

• Price volatility, which slows down its adoption as a currency of exchange.

But it also inspires innovations, such as the Lightning Network (to speed up transactions) and national bitcoinization projects.

Bitcoin has come an impressive way in just 15 years. From a simple cryptographic experience, it has become a pillar of global digital finance. Some compare it to digital gold, others see it as the people's currency for the 21st century.

Whether we believe it or doubt it, one thing is certain: Bitcoin has changed the way we think about money, finance, and economic sovereignty.
