甚麼是NFT？

NFT(Non-Fungible Tokens, 非同質化代幣)是一種數碼資產，一件實物跫過數碼形式在線上買賣，通常它們會使用跟其他加密貨幣相同的軟件，進行編碼。

雖然NFT只是存在了幾年，但它已經變得越來越受歡迎。2021年，這些數碼資產市值約410億元，超過整個藝術市場的總值。

與其他加密貨幣不同，NFT不可被取代，它們有獨特的識別碼，以茲識別。根據區塊鏈專家Arry Yu的說法，NFT的獨特性促使數碼稀少性。

任何人都可以免費在線查看這些圖像，甚至把它們截圖和儲存起來，那麼，為甚麼人們仍然願意花上百萬購買這些圖像呢？

這是因為NFT允許買家擁有原始物品，除此之外，它還包括內置認證，作為擁有權的證明，對收藏家來說，物品的數碼價值比它本身的價值更為重要。

怎樣進行NFT交易？

交易NFT並不是一門太空科學，要開始進行交易，首先，你需要一個與以太坊(Ethereum)兼容的加密貨幣錢包及一些以太幣(ETH)，你可以從各個交易所購買ETH，如Coinbase，然後傳送ETH到你在該交易所的錢包。

只要成功按指示設立加密貨幣錢包，你就可以利用這個錢包持有、傳送及接收加密貨幣，通過這個錢包，你就可以連接這個迅速發展的加密貨幣程式。全球有多個不同的NFT市場，在這裏，我們會集中討論全球最大的市場OpenSea，它的運作模式接近去中心化的eBay或淘寶，如要連接你的錢包到OpenSea，你可在它的網頁的右上角選擇’My Profile’，系統就會發出提示要求連接你的錢包。

 

完成後，你可開始瀏覽不同NFT產品，NFT的價錢由免費至數十萬元不等，稀有產品的價錢甚至可以訂得更高，而NFT亦可通過拍賣或即時購買賣出。

 

即使NFT是免費或便宜的，你仍然需要支付費用才能進行交易，在OpenSea，大部分數碼收藏品都使用以太坊區塊鏈(Ethereum Blockchain)，在NFT交易這些交易中，網絡會從中收取礦工費(Gas Fee)，礦工費則隨網絡的繁忙程度而有所不同。

 

選擇你喜歡的NFT，並確保你有足夠的ETH支付費用。購買後，你可以通過加密貨幣錢包查看你持有的NFT，直至你決定把它出售。

 

What is NFT? 

NFT stands for Non-Fungible Tokens which is a digital asset that is a kind of digital representation of real-world objects that can be bought and sold online. These are typically encoded with the same software used for all other cryptocurrencies. 

Although NFTs have been around for a couple of years, they are now becoming more popular due to their increasing popularity. In 2021, the market for these digital assets was valued at around $41 billion. This is more than the total value of the entire fine art market. 

Unlike other cryptocurrencies, NFTs are not fungible. They have unique identifying codes that can be used to identify them. According to Arry Yu, a blockchain industry expert, the unique nature of NFTs creates digital scarcity. 

Anyone can view the individual images—or even the entire collage of images online for free. So why are people willing to spend millions on something they could easily screenshot or download? 

Because an NFT allows the buyer to own the original item. Not only that, it contains built-in authentication, which serves as proof of ownership. Collectors value those “digital bragging rights” almost more than the item itself. 

 

How to trade NFT? 

 

Trading an NFT isn’t rocket science. At first, you’ll need an Ethereum-compatible crypto wallet and some ETH to get started. Buy some ETH from an exchange like Coinbase and send it to Coinbase Wallet. 

Follow the simple instructions to set up your wallet – which is a place you can keep some of your crypto, a place to send or receive it, and your portal to the growing universe of crypto apps. There are lots of NFT markets. For this tutorial, we’ll focus on OpenSea — which is the biggest of them all and works a lot like a decentralized eBay or Taobao. To connect your wallet to OpenSea, go to the website, click on the icon in the top right, and select “My Profile” — you’ll be prompted to connect your wallet.  

Once all are done you can Get browsing. Prices range from essentially free to hundreds of thousands of dollars or more for a rare item. Some items are sold via auction, while others can be snagged immediately via a “buy now” button.  

Even if the NFT is free or cheap, you’ll still have to pay fees to make the transaction happen. Most of the digital collectibles on OpenSea use the Ethereum blockchain, and the network charges a “gas” fee for transactions like NFT sales. Gas prices rise and fall depending on how busy the network is.  

Choose an NFT you like and make sure you have extra ETH to cover fees. Once you buy it, you can access the NFT via your crypto wallet until you decide to sell it.
