NFTs and Cryptocurrencies: the Ultimate Guide to Understanding Crypto NFTs

NFTs appeared in 2012 (with the Colored Coins project, then later with other projects such as Counterparty, Etherbots, Age of Chains and Rare Pepes, Cryptokitties, Cryptopunks…), and have skyrocketed since the late 2020’s all over the world.

What are we really talking about?

What is it used for?

Is it a craze or a true revolution?

Do they have a real value or is it a trend that will fade away as fast as Gangnam style?

Understanding NFTs, the virtual tokens

Our lives are increasingly dominated by digital technology, and NFTs are seen as the latest trend in cryptocurrency (along with Defi or decentralized finance). Its success translates into record sales in early 2021. NFT which translates to “non-fungible token” is a new kind of technology suddenly thrust into the spotlight. It represents an appealing concept that can earn millions for some artists.

What is an NFT, definition (or Non-fungible token)?

High profile individuals are interested in NFTs. This is the case of Twitter’s CEO or Elon Musk, the founder of Tesla. NFTs have broken records in the first quarter of 2021. These tokens are tamper-proof and transit through the blockchain. They are revolutionizing the way we think about digital assets and online ownership.

The notion of fungibility

NFT is an acronym for “Non Fungible Token”. This digital token can be a piece of digital art, music, a collector’s item or even a tweet.

This technology creates rarity in the digital world, which has been driven by copying until now.

These digital files have a usage value and a historical value. This is how the founder of Twitter sold his first tweet.

The unique feature of the token is that it is non-fungible, meaning that it has a unique nature and characteristics.

It cannot be replaced by another token. A token is considered fungible when it can be replaced by another one of the same nature (1 Bitcoin can be replaced by another, there is no difference. Each NFT is different and unique).

For example, cryptocurrencies are considered fungible tokens, just like a dollar bill.

Blockchain’s role

An NFT token is made non-fungible by a certificate of authenticity assigned by the blockchain. It is a tamper-proof digital property. The blockchain serves as a vast platform for data storage and information exchange. The exchanged data is transparent and secured by a global and decentralized system, which prevents any manipulation or hacking.

This storage technology works without the need for a controlling body.

The creator of an NFT can then encode it on the blockchain to make its characteristics unique.

The blockchain stores all the information about contracts, transactions or property titles. The cryptographic processes used by this technology make NFTs unforgeable and unique.

This technology allows to make a digital object unique, for the first time in history.

The role of cryptocurrency in NFTs

NFTs are non-fungible tokens that can be purchased through well-known digital currencies such as ethereum or wax.

Using an exchange platform like Coinbase or Binance is required to buy cryptocurrencies before acquiring NFTs. On the other hand, there are specialized digital art platforms like Nifty Gateway where users can make transactions in dollars.

How does it work?

It may seem a bit confusing at first.

NFTs primarily rely on the Ethereum blockchain.

This allows for the safe verification of all transactions (buying, selling, trading).

There are many websites or platforms to find NFTs and buy them. We talk about it in this article 😉

What is the difference between NFTs?

Non-fungible tokens “NFTs” appeared in 2017. They were introduced in the midst of a speculative bubble on cryptocurrencies. At the time, cryptokitties were the center of attention while the value of bitcoin was still $20,000.

The first crypto kitty sold that year was valued at over $117,000. It works the same way as the Panini albums did in its time. The distinctive feature of the Kitty was the presence of an NFT crypto which allowed to prove that it was unique.

A new paradigm in art?

The hype around NFTs reflects a new way of consuming art through cryptography. In fact, this new paradigm allows us not only to consume it, but also to collect it.

Potential buyers are ready to pay high prices for their favorite digital works and thus show that they own them. A new art market is being created before our eyes.

When buyer acquire an NFT, they don’t get the original work, but a copy of it located on the blockchain. The buyer is not the owner of the work of art. He doesn’t own the economic rights and can’t exploit it for commercial purposes.

NFT’s impact on the art market

According to analysts, NFT’s growth is not just a fad. It’s a true revolution that is impacting the art and collecting markets. The emergence of NFTs demonstrates the importance of being able to prove ownership of an object, whether it is physical or digital.

According to popular opinion, art is considered as something “beautiful” and cultural. But it is also a financial product which attracts a lot of investors. This is also the case with NFT cryptocurrencies.

Anyone can access a CryptoKitty and save the file on their computer. However, only one person is the actual owner and can prove it.

The NFT market has grown up to 300% in 2020 despite the global pandemic. The trade volume reached $250 million. Numbers are still exploding in 2021.

Auction houses quickly understood the scale of the NFT craze. The prestigious auction house, Christie’s, sold 5000 digital illustrations by the artist Beeple. Records are being broken everyday with NFTs. One of the most popular artists in this new cryptographic art era, managed to sell one of his collections at a value of $777,000.

A promising market for artists

NFTs are currently enjoying a favorable, even exceptional context. As a matter of fact, the cryptocurrency market is riding on a positive momentum in the last few months. The biggest crypto-currency investors own the equivalent of more than a billion dollars. The profits made by these investors are partly channeled into digital art. While the old rich put their money on Picassos and Monets, the new digital rich are investing in NFTs.

This new concept benefits artists as well. The digitalization of art has removed the need for intermediaries. Physical sales are still crucial to the survival of art. In most cases, intermediaries take a share of the sold works. Digital artists no longer need intermediaries. All they need is an Ethereum wallet to sell their art on specialized platforms.

Protecting one’s artistic works with NFT’s

A platform allows you to protect your artworks through blockhain technology and cryptocurrencies.  HUP market is a marketplace that allows artists to certify their works, locate copies on the internet and sell licenses and copyrights.

The world of collectors is full of NFT projects. You can now collect unique digital objects relating to Star Wars, Marvel, Disney, soccer, the NBA, and soon Pokemon or Formula 1.

The development of NFT will allow many enthusiasts to exchange digital products and create collections of things they feel passionate about. They will be able to exchange them, make them interact in a virtual world and in the real world, eventually.

NFTs in the music industry

The crisis affecting record sales has deeply changed the music industry. Artists have to fall back on live music to earn their living (not easy during a pandemic).

Streaming platforms still don’t pay artists properly for their music.

Artists have to find other sources of income.

Why not NFTs? It’s only logical, since they are instantly profitable; they are a classic sale but in a digital form, like selling a numbered vinyl directly to a buyer. Buying tokens requires going through an intermediary, such as OpenSea, which only receives a 2.5% commission on sales.

Snoop Dogg recently joined this market, and many other artists will follow.

How do NFTs work?

The way NFTs work depends on their original platform. Ethereum is the main cryptocurrency used to buy/sell NFTs.

There are no regulatory authorities on this market. Anyone can create or buy crypto NFTs. An NFT works like a trading card.

Trading and buying NFTs is similar to trading cryptocurrencies on Ethereum. However, transactions are carried out on its own platform. The user must then install a free extension like Metamask. The user can acquire NFTs once the extension is installed on the browser.

When users find an interesting offer on a website or find a potential buyer, they can connect directly to their Metamask wallet to complete the transactions.

Where to buy NFTs?

The art market is a very codified universe. It’s also a subjective market where individual taste prevails. There are two types of markets today.

The primary market is where a work is sold for the first time. A subsequent resale is done on the secondary market. Superrare dominates the primary market with respect to volume.

Here are my tips: Content protected


NFTs are bringing something never seen before: scarcity in the digital world.

It will definitely allow great things to happen.

However, there will also be profiteers, as in any market.

Some NFTs will eventually be worth nothing at all.

If you invest or get things that people will want to own, you will have something that matters.

For artists, this technology offers new ways to earn money without the need for a middleman!
