In 2022, NFTs have become a digital phenomenon. Since an NFT is unique, limited, and non-reproducible, interest in these digital objects increases massively. The driving force is a new “digital art market”. NFTs are auctioned off as works of art and sometimes reach six-figure sales prices on digital exchanges. In this list, you will find the most expensive NFTs of all time.

The advantages of NFTs in the art trade are obvious:

• NFTs can not be counterfeited or otherwise reproduced. They are unique and therefore have a high material but also emotional value for the owner.
• Thanks to digital marketplaces such as OpenSea , the digital art trade is open to everyone with internet access. Exclusive offline events with physical auctions can not offer such inclusion .
• The processes of auctioning and selling NFTs are extremely simple and very secure thanks to blockchain technology.

The popularity of NFTs doesn't stop with art, however. The influence and integration of non-fungible tokens are also increasing in other areas such as the music industry (songs as NFTs) or virtual real estate. A lot of money can now be made with NFT trading.

If you see NFT trading as an extreme opportunity in 2022, then you have the opportunity to make money trading digital artworks. NFT marketplaces are ideal for this. They specialize in buying, selling, trading and auctioning NFTs.

The most well-known trading venues of NFTs include the following platforms:

• OpenSea
• Rarible
• Super Rare NFT

There are also well-known crypto exchanges that mainly trade cryptocurrencies, but also have sections where NFTs can be traded:

• Binance
• FTX
• Crypto.com

OpenSea is a decentralized trading platform for NFTs on Ethereum. The platform has existed since 2018 and is growing as new NFTs are constantly appearing and being made available for NFT trading.

Most NFTs on Ethereum are derived from the ERC-721 standard. This implements the function setApprovalForAll. This function is called by the token holder and gives the transferred address the rights to transfer the NFTs. Anyone who logs into OpenSea with their Ethereum address calls this function and gives OpenSea the rights to transfer.

This is the reason why the tokens remain stored at the owner's address until the trade takes place. If there is an exchange, the OpenSea smart contract fetches the NFTs from the addresses of the buyers and transfers them to the buyer. OpenSea gets 2.5% of the price for each exchange.

If you have not yet had any contact with OpenSea and NFT trading, we recommend our OpenSea instructions for beginners.

Purchasing the NFTs you want is relatively easy. You look for the desired token on the website, click on it and pay the required price. You can also make the seller an offer for a better price. In doing so, one commits oneself to buy for the proposed price, or this is regulated by the smart contract. OpenSea currently supports trading with Ethereum, Polygon, and Klaytn.

1- Create a normal offer:

If you want to sell NFTs, you first have to give OpenSea access to the address where you keep your NFTs, as described above. There are several ways to sell NFTs. You can simply set a fixed price and wait for a buyer to respond.

2- Dutch Auction:

There is also the possibility to create a Dutch auction for NFT trading. At a Dutch auction, there is a starting price and a closing price. The final price is less than the starting price. Over time, the price decreases evenly to the final price. The price keeps going down until either the final price is reached or someone strikes at the current price. The falling price is effective in terms of game theory because the interested buyer is under pressure to grab the good before the others, he cannot wait long for a further falling price, so to speak, because of the competition.

For the Dutch auction, press the slider (red framed field) and further fields will appear. In the “Ending Price” field (yellow framed field) enter the ending price. And at “Expiration date” (framed in green) how long the auction should last.

In the example, a starting price of 0.22 Ether is set, the end price is 0.1 Ether and the duration of the auction is 5 days. Now the price falls steadily to 0.1 Ether in these 5 days unless someone buys at the current price. 0.12 Ether (0.22-0.1) price decrease in 5 days means the price then decreases by 0.001 Ether/hour.

The normal auction (“English auction”) is technically easier to set up. Click on “Highest Bid” above, enter the starting price and the end time (“Expiration Date”). Now the buyers can outbid each other from the starting price. Whoever has bid the most by the end gets the NFT.

You can also sell several NFTs of one type or series as a bundle. To do this, click on “Bundle” and select the desired NFTs. The bundles can then be sold as with the options already described.

OpenSea offers a referral bounty for every offer you create. This can be set when creating the offer (between 1% and 2.5% of the price). Anyone who sees the sales offer can have a referral link generated and spread it. If someone buys through this link, they get the bonus. However, you must have assigned an email address to your Ethereum address on the OpenSea off-chain.

Example: Someone sells a CryptoKittie for 100 Ether. You see the offer and have a buddy who might be interested. Now go to the offer and generate the referral link. If your buddy now buys the NFT with this link, you will get 1-2.5 Ether, depending on what the seller has set.

OpenSea is not only characterized by high usability or a large selection of NFTs, but also by versatile and secure payment options for NFT trading. The platform provides over 200 options for transactions. ETH is considered the default, but other tokens are also available, including:

• DAI and USDC stablecoins,
• wBTC,
• mana,
• REVV and SAND,
• WHALE,
• MEME

In recent years, OpenSea has developed into by far the largest NFT exchange. The marketplace offers the largest selection of NFT collections of any NFT marketplace. The functionality of the platform is kept particularly simple so that beginners can easily find their way around. Still, there are numerous different ways to sell your NFTs.

Monthly trading volume on OpenSea has grown to over $3.5 billion this year. With increasing popularity, this should continue to grow in 2022. So you can continue to earn a lot of money with NFT trading in the coming months.

News recently broke that a student from Indonesia became a millionaire with an NFT selfie. Can you do something like this too? Earning millions with NFTs is of course difficult and requires a bit of luck. However, if you have a creative streak and want to create digital artworks yourself, we advise using solid NFT platforms. Let's quickly recap what NFTs are, and recommend the best NFT marketplace around.

NFTs are basically digital ownerships tokens, that run on blockchains that support smart contracts, such as Ethereum. Their non-fungibility is similar to real-world contracts, where you can’t trade one contract to another, because the “actual content” differs from each other. Same things for NFTs, where you can't interchange them as their underlying “contract” changes with each one, hence their non-fungible nature.

You might be asking, what’s the use of NFTs if those applications are already being used? Well, the keyword is “decentralized smart-contracts“. There’s something to that word that makes you feel….secure, no? Here is a list of real-life applications:

• Identity Management
• Artwork
• Real Estate
• Media and Entertainment
• Gaming

OpenSea is now the largest of the NFT platforms. The platform allows you to create, trade, buy and sell digital artworks. OpenSea offers a variety of different collections, in which some NFTs are sold for the equivalent of several thousand euros.

OpenSea was founded in 2017 and has now replaced Rarible as the number 1 among NFT platforms. Nowhere else will you find such a wealth of different collections. The platform is extremely easy to use.

Rarible is also one of the largest NFT platforms. Rarible used to have a larger trading volume than OpenSea. Nevertheless, on Rarible you have a good opportunity to create your own NFTs and offer them for sale within a collection.

Rarible has a strong individual focus on the artists. The creation process for NFTs is very convenient and individual. With its broad support for multiple blockchains, Rarible is a key competitor for OpenSea.

FTX is one of the largest crypto exchanges in the world. In October, FTX began offering NFTs based on the Solana blockchain. These NFT collections caused quite a stir last year. Meanwhile, FTX has already topped up its NFTs with Ethereum-based collections.

FTX NFT is among the NFT platforms that are relatively new. As a new feature, the main platform FTX continues to push its new collections. You can also offer your NFTs here and, with a lot of luck, earn large sums with your own collections.
