THE CRYPTOCURRENCY

Bitcoin marked the emergence of a new concept in money. Its development is generally attributed to an individual or group using the pseudonym Satoshi Nakamoto. The project was presented in 2008 before the Bitcoin network was launched in early 2009. Its operation relies on decentralized technology, allowing transactions to be carried out without the need for a central bank or banking institution to validate each exchange.

The creation of new bitcoins is based on a mechanism called “mining,” which requires significant computing power. The protocol also stipulates a maximum supply of 21 million bitcoins, which is one of the fundamental characteristics of this digital asset. However, the cost and conditions associated with mining can vary depending on the network’s complexity, the price of energy, and the equipment used.

Since its inception, Bitcoin has gradually attracted the attention of investors, businesses, and traditional financial players. Its development has also contributed to the emergence of a much broader ecosystem encompassing numerous crypto-assets. Among the best-known projects are Ethereum and its ether, as well as numerous other digital assets based on different technologies and uses.

The rise of crypto-assets is part of a broader transformation of the digital economy. Like the internet, which has profoundly changed communication and exchange methods since the 1990s, blockchain technologies offer new infrastructures for recording, transferring, and verifying information and value in a decentralized manner. This evolution opens the door to numerous applications that go beyond simple monetary use.

One of the defining characteristics of crypto-assets lies in their exclusively digital nature. Unlike cash, they do not take the form of physical coins or banknotes. Their ownership and use rely on IT infrastructures and devices that manage the keys granting access to the assets. This characteristic is nevertheless part of a broader trend toward the dematerialization of traditional currencies, since the majority of contemporary banking transactions are also carried out electronically.

However, the operation of crypto-assets differs from the traditional banking system in its architecture. In the traditional banking model, transactions are recorded and managed within the accounting systems of financial institutions. In a blockchain, transactions are recorded on a distributed digital ledger according to the rules specific to the protocol in question. This organization allows for the transfer of digital assets between users without exactly replicating the operation of a centralized banking system.

The development of this ecosystem has thus given rise to a new asset class and numerous technological possibilities. It is nevertheless important to distinguish between different crypto-assets according to their characteristics, uses, operation, and risk level. Like any investment, their value can fluctuate significantly, and holding them should be considered in light of the risks inherent in this market.

Physical currency can be counterfeited, which is why banknotes incorporate numerous features designed to verify their authenticity. Cryptocurrencies operate on a different principle: their security does not depend on a physical medium, but on cryptographic mechanisms and computer rules that authenticate and record transactions.

In the case of Bitcoin, transactions are recorded on a blockchain, a distributed digital ledger that maintains a history of validated transactions. A copy of this ledger is kept by many network participants, allowing them to verify the consistency of the recorded information and contribute to the decentralized operation of the system.

When a blockchain is public, the recorded information can generally be viewed by anyone. Validated transactions are grouped into successive blocks, forming a chronological chain. Cryptographic mechanisms and consensus rules make any retroactive modification extremely difficult, as it would require challenging the data already recorded and meeting the conditions imposed by the protocol.

In the case of Bitcoin, block validation relies on the “proof of work” mechanism. Miners use computing resources to solve a cryptographic problem that adheres to the protocol’s rules. The resulting solution can then be quickly verified by other network participants. This mechanism helps protect the blockchain against manipulation attempts and maintain the ledger’s consistency.

The system’s security therefore relies on a combination of several elements: cryptography, decentralization, a consensus mechanism, and collective transaction verification. However, it is important to distinguish the robustness of the protocol from the security of the user themselves: protecting private keys, wallets, and access remains essential for securing the ownership of crypto-assets.

The traditional monetary system relies on a centralized organization in which commercial banks and central banks play a key role. Banks are responsible for maintaining accounts and processing payments, while central banks conduct monetary policy and hold the monopoly on issuing banknotes. The creation of electronic money by commercial banks takes place within a regulatory and prudential framework defined by the relevant authorities.

Cryptoassets such as Bitcoin are based on a different architecture. There is no central institution responsible for maintaining a single ledger or individually validating each transaction. Transactions are processed within a distributed computer network in which various participants contribute to the system’s operation and verification. This organization is generally referred to as a peer-to-peer (P2P) network.

The network’s operation is based on pre-established rules and a consensus mechanism. Participants apply the protocol’s rules to determine which transactions can be included on the blockchain. In the case of Bitcoin, miners play a unique role in this process: they group transactions into blocks and implement the proof-of-work mechanism necessary for their validation according to the network rules.

The creation of new bitcoins is also governed by the protocol. Unlike a currency that can be issued based on the decisions of a monetary authority, the number of bitcoins that can be created is determined by the network rules, with a theoretical limit of 21 million units. The reward given to miners also changes over time according to a mechanism defined by the protocol, particularly during “halving” operations.

This architecture does not, however, mean that the creation of bitcoins is free or unlimited. Miners must allocate computing and energy resources to participate in securing the network, but they cannot unilaterally decide to create additional bitcoins outside the protocol rules. Other network participants can reject blocks that do not comply with these rules.

Decentralization is thus one of the fundamental characteristics of Bitcoin. It profoundly alters the traditional role of financial intermediaries in the transfer and recording of value. Banks nevertheless retain an important role in the current crypto-asset ecosystem, particularly for exchanges between traditional currencies and digital assets, custody, payment services, and market access.

Transactions recorded on a public blockchain are associated with cryptographic addresses and amounts, then integrated into a distributed ledger accessible to network participants. In the case of Bitcoin, the transaction history can thus be publicly viewed, making it possible to trace movements between different addresses without automatically revealing the real identity of their holders.

Bitcoin is therefore more accurately described as a pseudonymous system than a truly anonymous currency. The addresses used do not directly correspond to a name or legal identity, but the movements recorded on the blockchain remain visible and can, under certain circumstances, be linked to a person or entity. This transparency is one of the elements that allows for verifying the consistency of the ledger and tracking the transaction history.

Another important characteristic of Bitcoin lies in its issuance mechanism. Unlike traditional currencies, whose circulating supply can fluctuate under the influence of monetary policies and the banking system, the Bitcoin protocol predetermines the conditions under which new units are created. The total supply is thus capped at 21 million bitcoins.

The amount of new bitcoins allocated to miners is gradually reduced over time. This phenomenon, known as the “halving,” occurs approximately every four years and halves the reward associated with creating a new block. The last bitcoin should theoretically be issued around the year 2140, assuming the current protocol continues to operate as intended.

This programmed limitation of the supply contributes to making Bitcoin a digital asset characterized by high scarcity. However, it does not mean that its price is guaranteed to increase: like any asset traded on a market, its value depends in particular on supply and demand, adoption, the economic climate, and the confidence of users and investors.

Like traditional currencies such as the euro or the dollar, crypto-assets can be used for transactions and, when accepted by participating merchants or service providers, to pay for goods and services. However, their operation relies on decentralized digital infrastructures, distinct from the traditional monetary system. This characteristic has long contributed to associating cryptocurrencies with speculative activities or illicit transactions.

Today, the use of crypto-assets has gradually expanded, particularly in online commerce and with a growing number of companies offering suitable payment solutions. Their use for everyday expenses with brick-and-mortar retailers remains more limited, but the evolution of payment infrastructures and the increasing adoption of digital assets are gradually broadening their potential applications. This democratization is also helping to shift public perception and further integrate crypto-assets into the contemporary financial ecosystem.

Access to cryptocurrency exchanges and services is becoming increasingly structured. Many providers implement identity verification and Know Your Customer (KYC) procedures to comply with regulatory obligations and help prevent fraud and money laundering.

DGB Global Capital places particular emphasis on these compliance requirements. As part of establishing a client relationship, verifications and supporting documentation may be requested to meet applicable obligations and contribute to a professional and transparent investment environment, in accordance with the requirements of the relevant authorities and regulatory frameworks.
