Learning Cryptocurrencies Easily in 2023

Today, it’s highly probable that you’re already familiar with cryptocurrencies. Their expansion since 2017 has attracted a growing number of investors. But are you aware of the technology underpinning these digital currencies, and the reasons behind their increasing appeal? In this article, we delve into the world of cryptocurrencies and blockchain technology, highlighting key cryptocurrencies worthy of investment in the current market.

How did blockchain (and cryptocurrency) originate ?

Cryptocurrency, as the name suggests, is a form of encrypted, primarily virtual currency. It was created with the main goal of overcoming the limitations of current banking system currencies, offering much faster and highly secure transactions between individuals.

Cryptocurrencies are independent of any financial institution, representing a key component of what is known as decentralized finance (DeFi).

The blockchain made its debut alongside Bitcoin in 2008, thanks to Satoshi Nakamoto. This technology is crucial for the existence of cryptocurrencies. With Bitcoin’s spread, blockchain gained prominence, leading to the emergence of new cryptocurrencies utilizing the same technology. Simultaneously, as cryptocurrencies began to rise with blockchain support, institutions and market players started exploring blockchain applications in various other fields.

What are the current and potential applications of blockchain technology

The most renowned application of this technology is in Bitcoin (BTC), the market’s most prominent cryptocurrency. This operates on a unique blockchain system, though it’s important to note that Bitcoin’s network has its own distinct blockchain.

It’s widely acknowledged that the genesis of blockchain technology is intimately tied to the birth of Bitcoin. This pioneering project not only popularized blockchain but also paved the way for the development of other cryptocurrencies. Some, like Ethereum, have even developed their own blockchains.

In this realm, blockchain’s primary role is in transaction verification.

This is achieved through blocks that record and store details, including the identification of digital currency transfers.

However, the utility of blockchain technology has expanded far beyond just currency exchange. Today, it is also applied in recording systems for :

  • Intellectual property;
  • Music;
  • Real estate contracts;
  • And more.

This includes the use of “Smart Contracts” – virtual contracts that encode rules and conditions directly into the blockchain.

How does blockchain technology function?

Blockchain technology is the backbone of online cryptocurrency transactions, including sending and receiving digital currencies.

Functionally, the blockchain acts like a ledger, meticulously recording details of various transactions. This “ledger” is public, with all information accessible and transparent. Transactions are verified and approved by multiple users, known as miners, ensuring accuracy and security.

Each set of verified transactions forms a block. Once a block is complete, it joins the existing chain of blocks, creating a continuous and tamper-resistant record. This distributed ledger is shared among all network participants, making fraud exceedingly difficult.

To further enhance security, each transaction on the network is encrypted before being stored in a block. The blockchain logs key data for each transaction, including its date, time, and the specifics of the transfer. These timestamps are based on UTC-0 (London local time). However, it’s important to note that these timestamps are not absolute and may have a margin of error.

Since the blockchain is decentralized, network users from various global regions can participate in validating blocks. Each block added to the network contains information about the transaction amount and its specifics, while maintaining the anonymity of the users involved. This makes it challenging to pinpoint who exactly validated, received, or transferred the currency.

Finally, each transaction generates a unique code known as a “Hash”. This Hash represents a record of the transaction on the blockchain. When a user makes a cryptocurrency transfer, this action produces a hash that can be verified against the blockchain to confirm the transfer’s validity.

What are the best cryptocurrencies to invest in for 2023 ?

The cryptocurrency landscape is dynamic, with new digital currencies emerging constantly. There are now hundreds of cryptocurrencies, each with unique features and benefits.

Among these, certain cryptos stand out for their faster scalability, making them attractive investment options. Here are some of the most promising cryptocurrencies currently :

  • Bitcoin ;
  • Solana ;
  • Polkadot ;
  • Avalanche.

Bitcoin (BTC)

Often referred to as the “mother” of all cryptocurrencies, Bitcoin has a significant lead over others. Its potential for long-term profitability remains high, continually drawing in investors.

Solana (SOL)

While Bitcoin is a popular choice, it’s not the only option for digital currency investment this year.

Solana presents itself as an excellent investment, akin to Ethereum but with potentially better capitalization. It offers a modern, scalable platform for smart contracts and decentralized finance, providing an alternative to some of Ethereum’s limitations.

Polkadot (DOT)

Polkadot stands out as a protocol aiming to unify various blockchains. It’s gaining traction, particularly in capturing a portion of Ethereum’s market share, by facilitating better interoperability between different blockchains.

Avalanche (AVAX)

As part of the “Ethereum killers” group, the Avalanche cryptocurrency offers scalable solutions and programming capabilities that outperform those of the Ethereum network. This makes AVAX an attractive alternative to Bitcoin and a contender in the digital currency space.

Risk Warning: Trading financial instruments and/or crypto-currencies involves high risks, including the risk of losing all or part of your investment, and may not be suitable for all investors. Crypto-currency prices are extremely volatile and can be affected by external factors such as financial, regulatory or political events. Trading on margin increases financial risk.


Before deciding to trade in financial instruments or crypto-currencies, you should be fully informed of the risks and fees associated with trading in the financial markets, carefully consider your investment objectives, level of experience, and tolerance for risk, and seek professional advice if necessary.
